e80faf3db6 QTimer: don't circumvent <chrono> safety net
By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
violate a principal design rule of <chrono>, namely that non-
narrowing conversions are implicit, but narrowing conversions
need duration_cast. By accepting any duration, we allow non-
sensical code such as

   QTimer::singleShot(10us, ...)

to compile, which is misleading, since it's actually a zero-
timeout timer.

Overloading a non-template with a template also has adverse
effects: it breaks qOverload().

Fix by replacing the function templates with functions that
just take std::chrono::milliseconds. This way, benign code
such as

    QTimer::singleShot(10s, ...)
    QTimer::singleShot(10min, ...)
    QTimer::singleShot(1h, ...)

work as expected, but attempts to use sub-millisecond
resolution fails to compile / needs an explicit user-
provided duration_cast.

To allow future extension to more precise timers, forcibly
inline the functions, so they don't partake in the ABI of the
class and we can later support sub-millisecond resolution by
simply taking micro- or nano- instead of milliseconds.

4cb614c7ab Apple OS: Handle QSetting strings with embedded zero-bytes
Saving strings with embedded zero-bytes (\0) as CFStrings would
sometimes fail, and only write the part of the string leading
up to the first zero-byte, instead of all the way to the final
zero-terminator. This bug was revealed by the code-path that
falls back to storing e.g. QTime as strings, via the helper
method QSettingsPrivate::variantToString().

We now use the same approach as on platforms such as Windows
and WinRT, where the string produced by variantToString() is
checked for null-bytes, and if so, stored using a binary
representation instead of as a string. For our case that
means we fall back to CFData when detecting the null-byte.

To separate strings from regular byte arrays, new logic has
been added to variantToString() that wraps the null-byte
strings in @String(). That way we can implement a fast-path
when converting back from CFData, that doesn't go via the
slow and lossy conversion via UTF8, and the resulting QVariant
will be of type QVariant::ByteArray. The reason for using
UTF-8 as the binary representation of the string is that
in the case of storing a QByteArray("@foo") we need to
still be able to convert it back to the same byte array,
which doesn't work if the on-disk format is UTF-16.

Add a class QWindowsRemovableDriveListener to
QWindowsFileSystemWatcherEngine listening to the WM_DEVICECHANGE messages
sent to the top level windows to detect insertion and removal of USB drives.
In addition, hook into QWindowsFileSystemWatcherEngine::addPaths() when
watching on removable drives, registering a notification for a
volume-lock-for-removal message on the internal window handle obtained from
QEventDispatcherWin32. When a request to lock the volume for removal is
received, remove the paths from the watcher, enabling removal.

The class instance is set as a dynamic property on the QFileSystemWatcher where
it can be retrieved from clients. This is primarily intended for use by
QFileInfoGatherer/QFileSystemModel.

7c1d640c0c stop exporting the library versions
all users of this functionality have been removed, and not emitting the
version info saves quite some noise from the generated files.

the reason why the users have been removed is that it was unreliable in
the first place: if a dependency is found without pkg-config, no version
information would be available.

the extraction of the version via pkg-config itself is kept in place, as
configure tests could be potentially optimized by utilizing it.

this reverts much of commit 48b4e0bf6f.

9a088e7869 use helper libs via QMAKE_USE
for that, qt_help_lib.prf gains the ability to write "external module
pri" files that contain suitable information for QMAKE_USE.

these files have a bunch of limitations:
- they are not installed, because a) they are not relocatable and b) the
  helper libs' headers are not installed, either
- it won't work with qmake -r, which is ok, as qt5 does not build with
  qmake -r anyway
- deps are not transitive, neither at build nor at use time

the freetype, harfbuzz-ng, pcre, and png helper libs have been adjusted
accordingly, and their uses replaced with QMAKE_USE instances. this also
allowed inlining the now trivial {harfbuzz,pcrc,png}_dependency.pri
files. freetype_dependency.pri remains due to its funkiness.

particular, ActiveQt. When an ActiveQt server is loaded, it tries to
mimic the behavior of calling QCoreApplication::exec() by setting
QCoreApplicationPrivate::in_exec = true. However, when unloading the
DLL it is necessary to call the same clean-up (e.g. deferred delete)
that QCoreApplication::exec() does. Extracting the cleanup in a separate
function means implementation does not have to be duplicated.

fd7e00aff5 Don't truncate QDateTime milliseconds when storing QSettings on Apple platforms
The fix is trivial, but the patch adds a new QSettings tests that iterates most
of the QMetaTypes and verifies that storing and retrieving them again gives the
same value. This is a more complete test than the testVariantTypes tests, which
is limited to a subset of the QVariant types. The new tests borrows logic from
the QMetaType test machinery.

QSettings has been Q_ENUM'ified in the process, for improved debug output.

Note that on backends such as the INI backend, the metatype of the QVariant read
from the settings will be a string, so it won't match the input QVariant type,
but the result of converting that to the original value type should still work.

bdb81d0bd1 Avoid re-use of QFileSystemMetaData instance in dir entry listing
We've observed that on machines with SELinux installed but disabled, the
behavior of readdir() changes slightly. In the case of tst_qdir's
entryList QDir::Hidden test case, the listing of the directory contents
returns DT_UNKNOWN for the files and (broken) symlink(s) that are
present. When SELinux is enabled, we do see DT_REG and DT_LNK. Our
fallback to DT_UNKNOWN however resets merely the knownFlags, it does not
reset entryFlags, as all the other cases do.

The bug comes when QDirIteratorPrivate::advance() re-uses the
QFileSystemMetaData instance across iterations, and this way we get the
entryFlags values from a previous iteration (with != DT_UNKNOWN) into
the evaluation of an entry with DT_UNKNOWN.

The more conservative approach to fixing this is here by assuming that
QFileSystemMetaData is not designed for re-use and re-initialize it
explicitly in the iteration.

permissions such as Location permissions cannot only be granted via
Android's Manifest files. An additional runtime check/request system

the first time a privileged function is called. Such user prompt
responses
are returned to the current application via the
Activity.onRequestPermissionsResult(..) callback.
This change add Qt API to nicely check & request permissions. For now
this is private

compontents. Later Qt versions will introduce a public API to
QtAndroidExtras.

6b3845320a QLocale: Add option to pad numbers with trailing zeroes
EcmaScript mandates that number-to-string functions pad the resulting
strings with zeroes, up to the requested precision. QLocale actually
supports this, under the disguise of the "Alternate" flag, used by
QString::asprintf().

We split this flag into the three options it actually represents and
make IncludeTrailingZeroesAfterDot available as a NumberOption. This
allows us to generate numbers in an EcmaScript compliant way.

In addition, a symmetrical option to reject trailing zeroes when
parsing strings to numbers is added.

allow generating strings from doubles in accordance to EcmaScript's

a54d44298f QLatin1String: Fix UB (nullptr passed) in relational operators
Found by UBSan:

  qstring.h:1160:44: runtime error: null pointer passed as argument 1, which is declared to never be null
  qstring.h:1160:44: runtime error: null pointer passed as argument 2, which is declared to never be null

Fix by avoiding the memcmp() calls if there's a chance that they
might be called with nullptr.

While at it, also implement !=, >, <=, >= in terms of ==, <,
and add a test, because this particular UB was not fingered by
any of the QtCore test cases, but by a Qt3D one.

42f974f56b Add QArrayData::reallocateUnaligned for QString and QByteArray
This function reallocates a QArrayData block with realloc() but, as
the name says, it's only valid for types that do not increase the
alignment requirements. I don't think it's worth doing this for types
that do increase the alignment requirements, since we don't know the
alignment of the pointer returned by realloc(). If the new pointer
modulo the alignment is different from the old pointer modulo the
alignment, we'd have to memmove data around, which would be quite
inefficient (realloc might have memcpy'ed already and this memmove
would copy data to nearby).

This function is intended to be used especially in QString and
QByteArray, which were already using realloc() on pointers created by
QArrayData::allocate.

2a6bea7a55 qcompilerdetection.h: retract Q_COMPILER_DEFAULT_MEMBERS for MSVC < 2015
Earlier versions of the compiler cannot default
move special member functions, even though we
also define Q_COMPILER_RVALUE_REFS for them.

Fix by retracting the less-often-used of the
two compiler feature defines.

Q_COMPILER_DEFAULT_MEMBERS is not used outside
QtBase in neither 5.6 nor 5.7 (5.8 is not
released at this time, so wasn't considered).
The same is true of the dependent macros
Q_COMPILER_DEFAULT_DELETE_MEMBERS and
Q_DECL_EQ_DEFAULT.

In QtBase, the three uses are:
1. in QAtomic*, where the user also requires
   Q_COMPILER_CONSTEXPR, which is not defined
   for any MSVC at this time,
2. for QEnableSharedFromThis, which is a class
   template with an alternative {} implementa-
   tion of the default constructor, and uncon-
   ditional user-defined copy special member
   functions.
3. The test of the corresponding functionality
   in tst_compiler, which this commit amends.

That means that neither of these two only uses
of the macro in Qt libraries are affected by
the change.

The reason we do this change, then, is that in
the future, we want to be able to more easily
restore move special member functions for
classes for which they are suppressed due to
user-defined dtors or copy special member
functions.

84830fc07d QLockFile::tryLock: prevent over-sleeping in certain cases
The sleep time increases exponentially, but we never checked whether the
time to sleep was less than the remaining time. For example, if timeout
was 4000 ms on entry, we'd progressively sleep 100 ms, 200, 400, 800,
1600 ms. At this point, the accummulated sleep time would be 3100 ms and
the next sleep should be no more than 900 ms.

Prior to this change, the tryLock() would then proceed to sleep 3200 ms,
for a total wait time of 6300 ms, or 57.5% above the timeout provided by
the user.

d875a04174 QtJson: simplify/add missing relational operators involving Latin1String
As noted by Mat Sutcliffe <oktal3700@gmail.com>, there were
no relational operators for Latin1String/QLatin1String and
String/QLatin1String mixed comparisons, leading to implicit
conversions from QL1S to QString in Entry::op==(QL1S).

This patch fixes half of the issue, by providing the operators
for Latin1String/QLatin1String. In doing so, it cleans up their
definition (non-members, non-friends, delegating to existing
QL1S operators where possible, passing both {Q,}Latin1String by
value, as they're both Trivially Copyable and small).

A follow-up patch will deal with String/QLatin1String
comparisons. It will be not quite as straight-forward as
this patch, since we don't, yet, have QStringView, the
UTF-16 equivalent of QL1S, available.

Amends a5159cc50a.

680ec54a76 QMutex: Make freelist() return a real global static
Since Qt 5.6.0, some applications such as Kate (built with clang, libc++
and libcxxrt) on FreeBSD occasionally crash with the following error
message on exit:

    QMutex::lock(): sem_wait failure: Invalid argument
    [or pthread_cond_wait in the 5.6 branch]

Investigation by Gleb Popov, Thiago Macieira and Olivier Goffart has
shown that this is caused by the fact that QDBusConnectionManager is a
Q_GLOBAL_STATIC (so it will be destroyed with all the other
Q_GLOBAL_STATICs in the reverse order of construction). In the
Q_COMPILER_THREADSAFE_STATICS case, freelist() also returns a
function-level static that is constructed on first use, so it may be
destroyed earlier than the QDBusConnectionManager object, making it
impossible to lock a contended mutex.

We now make freelist() return a global static, so that it is always
destroyed after QDBusConnectionManager and other function-static
variables.

4f6f0cd4c9 Bypass a bug in gcc 4.7 for QAtomicTraits::isLockFree()
It's not possible to build Qt with gcc 4.7 since
aca0e367be because of the bug
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53473 that doesn't
allow to specialize static members declared both as constexpr
and noexcept. That commit was made after 5.7.0 and it introduced
QAtomicTraits::isLockFree() with these specifiers.

Remove the noexcept specifier to fix building.

606924132f Add support for safe feature checking at compile time
Added a qtConfig(feature) function to qmake, and a QT_CONFIG(feature)
macro. These can safely check whether a certain compile time feature of
Qt is enabled or not.

For this to work the feature has to have a publicFeature or
privateFeature output in the configure.json file.

In pro files, please use the qtConfig(feature) test function
instead of checking contains(QT_CONFIG, feature), as the latter
will be unreliable with the upcoming modularization (it requires a
load(qt_module_config) before doing any such checks). Note that
feature names are now lowercase, and identical (except for hyphens
versus underscores currently) in the pro and c++ files.

This makes the logic easier to follow, as we avoid all double negations,
and most importantly, QT_CONFIG and qtConfig are implemented in a
way that you'll get a build error for a mistyped or non-existent
feature. This will also prevent accidental use of a widget feature
in gui in the future.

This gives us complete symmetry between the handling in pro and
c++ files.

this enables us to remove the early forwarding header generation from
qtbase.pro, and rely wholly on the regular mechanism from syncqt +
qt_module_headers.prf.
another advantage is that we can be sure that the bootstrapped namespace
is not polluted by the target feature configuration.

8dc45d5b7c Deprecate Q(Persistent)ModelIndex::child
Due to how invalid model indices are handled in Qt, child() is unsuitable
for general purpose usage. In particular you can never get a top level
item in the model because the root model index by definition hasn't got
a pointer to the model it belongs.

That makes child() useless for anything but tree models (and even there
you'd need to special case your code anyhow).

been deprecated due to its lack of generality.
Use model->index(row, column, index) instead.

I am not convinced toUpper/toLower is a generally sound solution here;
however, QLocale doesn't make the upper/lower case distinction this
parser does and a bug report shows tr() isn't doing an adequate job.

009f1f2812 QString: fix regression comparing null QString with null const char *
Commit 4a40c717f3 optimized
QString::compare_helper(QChar*, int, char*, int), but got
the case wrong where the rhs is null, but the lhs is empty,
not null (which is the case even with a null QString, as
QString().constData() != nullptr). The correct result in
this case is 0, since in Qt empty and null strings compare
equal.

Fix by checking the length of lhs, not its pointer.

91a2c8630b QUrl::resolved: keep treating file:name.txt as relative for now
8a33077 made QUrl::resolved() follow its documentation ("If relative
is not a relative URL, this function will return relative directly.",
where relative means scheme is empty).
However there is much code out there (e.g. qtdeclarative) which relies
on QUrl::fromLocalFile("fileName.txt") to be treated as relative, so
for now, we still allow this (in Qt 5.6.x). For Qt 5.8, this commit will
be reverted.

[ChangeLog][QtCore][QUrl] [EDITORIAL: replaces 8a33077] QUrl::resolved()
no longer treats a URL with a scheme as a relative URL if it matches
this URL's scheme. For now it still treats "file:name.txt" as relative
for compatibility, but be warned that in Qt 5.8 it will no longer
consider those to be relative. Both isRelative() and RFC 3986 say that
such URLs are not relative, so starting from Qt 5.8, resolved() will
return them as is.

for validation. Non-NULL str.string() may yet leave us
with a useless str.unicode(), which is the actual problem here;
whereas !str.isNull() does really confirm that str.unicode()

Such test prevents situation like:

const QString a;
QString b;
b.append(a); // b.isNull() == true
b.append(QStringRef(&a)); // b.isNull() == false

Auto test updated: create QStringRef from QString directly, without
any condition.

4a40c717f3 Optimize QString::compare_helper(QChar*, int, char*, int, cs)
... by using the recently-added QUtf8::convertToUnicode()
and a QVarLengthArray instead of QString::fromUtf8().

Like elsewhere in QString, use a QVarLengthArray<ushort>
instead of the more natural <QChar> to avoid instantiating
another QVLA.

Assume that length2 is usually set to a non-negative value.
Not because that's necessarily the frequent case, but
because a negative length2 leads to an expensive strlen,
that usually dwarfs the additional branch cost.

Check for data2 == nullptr early to avoid having to check
it later twice.

c0637c0298 QObject::connect: allow to disable narrowing of the connection arguments
One of the good features of the new connection style is that
implicit conversion is performed for the connection arguments.

However, this is also a bad feature when it comes to the old
C remnants in the C++ language: for instance, doubles implicitly
convert to ints, possibly losing precision (and GCC/Clang do not
even warn about those under -Wall, only MSVC does) or even
triggering undefined behavior.

For this reason, when using braced initialization, C++11
disables narrowing conversions or floating/integral conversions.
Use this feature when checking the arguments of a PMF-style
signal/slot connection. Technically this makes the program
ill-formed, however GCC still accepts it (but at least
warns under -Wall).

Hence, add a way to disable these implicit conversions.
This is a opt-in and guarded by a macro, as it's a source
incompatible change.

[ChangeLog][QtCore][QObject] The
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT macro has been added.
When using the new connection syntax (PMF-based) this macro
makes it illegal to narrow the arguments carried by the signal,
and/or to perform floating point to integral implicit
conversions on them. When the macro is defined,
depending on your compiler a QObject::connect() statement
triggering such conversions will now fail to compile.

49c8923282 QSortFilterProxyModel: Don't forward the hint from source's layoutChanged signal
We can't forward a VerticalSortHint or HorizontalSortHint hint, because we might
be filtering extra items.

The documentation of QAbstractItemModel::LayoutChangeHint states:

    Note that VerticalSortHint and HorizontalSortHint carry the meaning that
    items are being moved within the same parent, not moved to a different
    parent in the model, and not filtered out or in.

And some of the views rely on this assumption (QQmlDelegateModel for example)

What happens in the test is the following:
- 'model' emit the dataChanged signal when its data is changed.
- 'proxi1' QSortFilterProxyModelPrivate::_q_sourceDataChanged does not forward
  the dataChanged signal imediatly, it will instead first re-sort the model and
  call layoutAboutToBeChanged / layouChanged with the VerticalSortHint
- 'proxy2' would forward the layoutAboutToBeChanged with the hint, but in
  QSortFilterProxyModelPrivate::_q_sourceLayoutChanged, it will redo the mapping
  which will cause the changed data to be filtered.
So proxy2 can't forward the VerticalSortHint as it removed rows in the process.

f24cc53cc2 Fix for race condition in signal activation
There was a race condition between QObject::disconnect() and
QMetaObject::activate() which can occur if there are multiple
BlockingQueued connections to one signal from different threads and
they connect/disconnect their connections often.

What can happen in this case is:
T1 is in activate() method and T2 is in disconnect() method

T1                          T2
locks sender mutex
selects next connection
unlocks sender mutex
                            locks sender mutex
                            sets isSlotObject to false
creates QMetaCallEvent      derefs connection
posts event

Two things can happen here:
1. Connection can still be valid, but it will have isSlotObject==false
and callFunction will be used instead of slotObj
2. Connection can already be invalid

To fix it mutex unlock should be moved after QMetaCallEvent creation.

Also there is another case, when we don't disconnect but delete the
receiver object. In this case it can already be invalid during
postEvent, so we need to move mutex unlock after postEvent.

3c6a7a96ef QRingBuffer: add packet mode
As a special case, setting the value of chunk size to zero forces
QRingBuffer to produce a separate QByteArray on each call which
appends the data. So, this enables a packet mode where portions of
data are stored independently from each other.

dd59118b87 move c++11 test into qcompilerdetection.h and make it stricter
it positively makes no sense to have a configure test which will be
never reached due to the configure/qmake bootstrap failing with a
slew of totally unhelpful error messages.

pre-standardization partial c++11 implementations are now rejected,
except for VS2013, which is still sufficient despite not announcing full
compatibility.

b5153d5bfa Windows: Disable unsupported C++11 features with Clang-cl and ICC
Whenever someone installs Clang or the Intel compiler on Windows, it's
very likely that the compiler will be much newer than the MS headers
that came with the installed Visual Studio version. So let's make sure
we disable the C++11 features that the MS headers don't support
properly.

For example, MS's <limits> header supplied with VS 2013 doesn't mark the
max() function as constexpr, resulting compiler errors in uses of that
function in Qt code declared with Q_DECL_CONSTEXPR:

qdeadlinetimer.h(62,13) :  note: non-constexpr function 'max' cannot be used in a constant expression
        : s(std::numeric_limits<qint64>::max()), ns(0), type(type_) {}

e6034a4740 Make sure JNI_OnLoad is not called more than once
Since Android 5.0 Google introduce a nasty bug[1] which calls
JNI_OnLoad more than once.
Basically every time when a library is loaded JNI_OnLoad is
called if found, but it calls *again* JNI_OnLoad of its .so
dependencies! So, JNI_OnLoad of libQt5Core.so gets called may times,
this is not a problem as long as it's called from Qt's java delegate
class loader. The problem is that the application .so file *must* be
called from default class loader to allow the user to find his custom
Activity/Service stuff.

c14c149b51 Fix QTemporaryDir to handle Unicode characters on Windows
For platforms not providing mkdtemp(), QTemporaryDir relied on an implementation
of q_mkdtemp() operating on char *, converting back and forth using
QFile::encodeName()/decodeName() when passing the name to QFileSystemEngine.
This caused failures on Windows (which uses "System"/Latin1 encoding)
for names containing characters outside the Latin1 space.

Reimplement q_mkdtemp() to operate on QString, which avoids the conversions
altogether and also enables the use of larger character spaces for the
pattern.

Add tests.

da04322b4c Make moc obey the preprocessor environment variable for include paths
C preprocessors augment their standard list of include paths from the
environment: Unix preprocessors use $C_INCLUDE_PATH (for C) and
$CPLUS_INCLUDE_PATH (for C++), plus CPATH for both, whereas MSVC uses
the an environment variable simply called "INCLUDE". Handling this for
MSVC is particularly important because the VCVARSALL.BAT script sets the
necessary #include paths in the environment for important things.
Without that being parsed, moc won't find some #defines, like
WINAPI_DESKTOP_FAMILY.

[ChangeLog][moc] qmake and moc now cooperate to use the Visual Studio
environment variables (set by the VCVARSALL.BAT script) to find system
include files. A possible consequence is that moc parses application
headers slightly differently, depending on #if conditions that depended
on macros that previous versions had not seen #define'd. Implementers of
other buildsystems are advised to pass the --compiler-flavor=msvc option
to moc.

c2f4705f23 Add qHash(QHash) and qHash(QMultiHash)
The hash function is carefully designed to give the same result
as the straight-forward implementation of qHash(unordered_map),
which we'll probably add at some point, namely: std::accumulate
over a container of std::pair.

This is one reason to use std:: and not QPair in the implemen-
tation of qHash(QHash). The other is that qHash(QPair) uses a
bad hash combiner, which may xor out the 'seed' from the result.

We can't fix that until Qt 6, but the qHash(std::pair) overload
uses the well-known boost::hash_combine algorithm (implemented
in Qt as QtPrivate::QHashCombine), so we can use that.

I also trust std::pair to work without problems with reference
template arguments, while QPair only very recently gained a very
basic auto-test for reference parameters.

[ChangeLog][QtCore] Added qHash() overloads for QHash, QMultiHash.

e21bf5e6b3 QString::replace(): protect sought text and replacement
When replacing each copy of one text with a copy of another, we do so
in batches of 1024; if we get more than one batch, we need to keep a
copy of the sought text and replacement if they're part of the string
we're modifying, for use in later batches.

Also do the replacements in full batches of 1024, not 1023 (which left
the last entry in an array unused); marked some related tests as
(un)likely; and move some repeated code out into a pair of little
local functions to save duplcation.

Those new functions can also serve replace_helper(); and it can shed a
const_cast and some conditioning of free() by using them the same way
replace() now does.  (There was also one place it still used the raw
after, rather than the replacement copy; which could have produced
errors if memcpy were to exercise its right to assume no overlap in
arrays.  This error is what prompted me to notice all of the above.)

Added tests.  The last error proved untestable as my memcpy is in fact
as fussy as memmove.  The first two tests added were attempts to get a
failure out of it.  The third did get a failure, but also tripped over
the problem in replace() itself.  Added to an existing test function
and renamed it to generally cover extra tests for replace.

f8dc769655 QMacTimeZonePrivate - correctly initialize m_nstz data-member
The default ctor never initializes m_nstz but calls init with
[NSTimeZone systemTimeZone].name. Init (re)sets m_nstz _only_
if this ianaId is in [NSTimeZone knownTimeZoneName], which is not guaranteed
(a good example is "US/Pacific" that can be returned by systemTimeZoneId() -
the similar problem is described in [*]. Set m_nstz to nil in ctor,
so if 'init' fails we still have a valid (nil) pointer.

The const qualification prevented toUpper() etc from
calling the rvalue overloads of the corresponding QString

object, the rvalue overloads can re-use the object's
capacity for storing their result, saving up to one memory
allocation per QStringBuilderCommon::to*() invocation.

cba3378732 Make QDateTime's default constructor not allocate memory on 32-bit
Commit fb498a6519 introduced the short
datetime optimization, but it accidentally removed the optimization from
Qt 5.7 that made QDateTime's default constructor not allocate memory.
Instead of bringing back the Q_GLOBAL_STATIC that was used, let's use
the short date time optimization on 32-bit too.

The CanBeSmall constant remains false on 32-bit systems, but judicious
non-use of that constant in a few functions allows 32-bit systems to use
the optimization. We still say that any date/time value is "unsmall", as
there's no sense in calculating whether the date is between 1970-01-01
and July 14 of the same year.

b6345a515b QStorageInfo: update the algorithm for ignored filesystems on Unix
Use the criterion that GNU coreutils' df uses: if the total size of the
filesystem is zero, then it's pseudo. After all, if it contains files in
a zero-sized volume, it has to be pseudo; if it contains nothing, then
it's not very useful anyway.

This would have caught most Linux pseudo-fs anyway, but the mount point
check beforehand allows us to skip quite a few statfs() syscalls.

The new algorithm also solves the following cases which had been
mistakenly interpreted:
 * fuse and ZFS (source devices don't usually start with /)
 * pseudo-fs that were mounted from a device starting with /
   (the source device is usually ignored by the OS)

This change is not testable automatically. Manual testing shows it still
reports the same entries it used to on Linux, plus now shows FUSE
(sshfs) mounts.

3c93286f08 QDataStream: unify deserialization of containers
Serialization of the Qt container classes is accomplished by breaking
up the data into primitive units. On the receiver side, these units
should be read atomically to guarantee integrity of the container.

Deserialization procedures for QHash and QMap were already implemented
in accordance with this strategy and have the following behavior:

 - a previously latched error status is saved for the caller. This
   overrides possible different errors in the current read. This
   is consistent with the treatment of primitive types.
 - if an error occurs during the deserialization, the container is
   cleared.

To make the API consistent, this patch adjusts the behavior of QList,
QLinkedList, QVector, and QSet deserialization. On the implementation
side we accomplish this with a private StreamStateSaver RAII class that
consolidates the handling of the stream status for all containers.

[ChangeLog][Important Behavior Changes][QtCore][QDataStream] Incomplete
reads of Qt containers are now handled same way as for primitive types,
meaning that previous errors are latched.

bff15c547e QDateTime: introduce {to,from,set,current}SecsSinceEpoch
These new functions use a 64-bit integer in the API, instead of the
broken 32-bit unsigned integer that the previous xxxTime_t functions
used. That was a design flaw when the API was introduced back in Qt 4.2,
so I'm deprecating the API and slating it for removal in 6.0.

The changes to qfilesystemmetadata_p.h and quuid.cpp are necessary to
build the bootstrap library. The rest of the adaptation to the new API
will come in the next commit.

[ChangeLog][QtCore][QDateTime] Introduced toSecsSinceEpoch,
fromSecsSinceEpoch and setSecsSinceEpoch functions, which use 64-bit
integers to represent the number of seconds.

[ChangeLog][QtCore][QDateTime] The toTime_t, fromTime_t and setTime_t
functions are deprecated and will be removed in Qt 6.0. For new code,
use the equivalent functions with "SecsSinceEpoch" in the name, or the
equivalent ones with millisecond accurancy that have existed since
Qt 4.7.

9caac0f176 Add OpenBSD to list of targets that can't use --no-undefined in qtcore
A prior commit has already added the resetting of QMAKE_LFLAGS_NOUNDEF
in corelib.pro for FreeBSD due to environ(7) not being part of libc.
OpenBSD has the same issue, so add it to the list of BSD systems
affected for resetting the flags for qtcore.
