ce08318a46 Add QThreadPool autotest to detect stale threads after tryTake
This test makes sure that we do not introduce a regression where the
threads exited the inner loop over the queue before the queue was
empty. This was triggered by calling tryTake at least maxThreadCount
times, which left the same number of null pointers in the queue
and caused the inner loop to exit too soon for all the threads.

bbc68dc815 Fix tst_QFile::useQFileInAFileHandler for systems using resources for test data
Resource files are extracted to m_dataDir in tst_QFile::initTestCase.
Instead of trying to access the file from the resource on systems that
use qrc for bundling the test data, we have to use the files that were
extracted at the beginning of the test.

ad36da8ff4 testlib: start sharing common helper functions
... by moving them in QTestPrivate namespace (qtesthelpers_p.h). This
header file is a convenient staging area for helper APIs, eventually
some could be moved to public QTest API.

This header file utilizes the same pattern as other qtestlib header
files - wrapping functions with QT_${LIBNAME}_LIB to automatically
enable certain APIs based on what is in the projects dependencies,
e.g. QT += widgets.

9574436666 QUrl: make sure setPort(nonnegative) is taken as part of authority
There were a couple of corner cases where doing setPort() would result
in QUrl thinking that an authority was not present. Since the full URL
parsing implies that a host is always present if the authority is
present, then we also imply that setting the port number makes the host
be present too.

f62768d046 QUrl: re-fix the setPath("//path") case leading to scheme://path
Commits aba336c2b4 (in Qt 5.2) and
aba336c2b4 (in 5.6) both tried to deal
with this problem, with different levels of success. This is the third
attempt (and hopefully the charm).

Instead of modifying the path that the user provides, go straight ahead
and declare it invalid. This is supported by RFC 3986, which declares
this expansion impossible:

   relative-part = "//" authority path-abempty
                 / path-absolute
                 / path-noscheme
                 / path-empty
   path-abempty  = *( "/" segment )
   path-absolute = "/" [ segment-nz *( "/" segment ) ]
   path-noscheme = segment-nz-nc *( "/" segment )

The "path-abempty" and "path-noscheme" cases are the two issues we
already handle. This commit adds the third one: path-absolute, which
requires that the first segment of the path be of non-zero length.

That is, it is now possible again to have http://example.com//path
constructed piece-wise, without it producing http://example.com/path.
Additionally, it catches the case of http://example.com//path parsed
from full URL then followed by setAuthority("").

Also add a test that makes sure tryTake() is safe to

tries to use nullptr entries.

0f11fab6f7 Fix resolution of relative symlinks from relative path on unix
Consider the following:
/root/target - a file
/root/path/link -> ../target
/root/path/other/exe - executable

Running from /root/path/other.

exe is:

#include <QDebug>
#include <QFileInfo>

int main()
{
    qDebug() << QFileInfo("../link").symLinkTarget()
    return 0;
}

The link references /root/target, but the current output is
/root/path/target.

The link doesn't depend on the PWD. It depends on its own directory.

af7e756155 Return "en" for QLocale::c().bcp47Name()

in section 2.1 which specifies a minimum length of 2 characters for all language
tags.

[BCP47]: https://tools.ietf.org/html/bcp47

This patch changes the return value to "en" seeing as the documentation for
QLocale::Language states that the C language is identical in behavior to
English.

As the files are packaged into the binary, they have to be
extracted, before they can be ::open'ed.

65a317e674 Use QMap in QProcessEnvironment so variables are sorted
The motivation for this change is to make it simple to pass a
correctly sorted environment block to Win32 CreateProcess(). It is
also nice in other contexts that the environment variables are
sorted. The change is made for all platforms. This keeps it simple and
the only ill effect is slightly slower lookups.

Concerning the environment block passed to Win32 CreateProcess:

The environment block that is passed to CreateProcess() must be sorted
case-insensitively and without regard to locale. See
 https://msdn.microsoft.com/en-us/library/windows/desktop/ms682009(v=vs.85).aspx

The need for sorting the environment block is also mentioned in the
CreateProcess() documentation, but with less details:

26fd805f50 macOS/iOS: Correctly ignore punctuation in QCollator
When punctuation is ignored then the kUCCollatePunctionSignificantMask
should not be set. This was originally thought to not be working due to
a bug on the Apple platforms, but this is not the case.

[ChangeLog][Platform Specific Changes][macOS][iOS] QCollator now
respects the ignorePunctuation property on Apple based platforms
correctly.

147aa29162 Fix sending UTC-offset QTimeZones through QDataStream
QTimeZone("UTC") should be valid, as "UTC" appears in the list of
availableTimeZoneIds(), and tst_QTimeZone::dataStreamTest() constructs
timezones like this, which are considered valid.

The internal representation of a QTimeZone("UTC") as created by
QTimeZone::QTimeZone(const QByteArray &ianaId) is a QUtcTimeZonePrivate
which isValid(), so the containing QTimeZone isValid() too.

When QTimeZone is serialized into a QDataStream, it calls
tz.d->serialize(ds) which is QUtcTimeZonePrivate::serialize. This
writes QStringLiteral("OffsetFromUtc") followed by the IANA ID and
the offset (etc.) to the datastream.

When QTimeZone is deserialized it looks for this marker string, and if
present, it passed all of the parameters to the QTimeZone constructor
(not just the name). However, that constructor does not support standard
IANA timezones (only custom ones), and when it detects that the supplied
IANA ID is actually listed in availableTimeZoneIds(), it leaves the
pointer to the QTimeZonePrivate uninitialized (NULL), which leaves
the QTimeZone invalid (isValid() returns false).

Thus, a valid timezone which was serialized and then deserialized has
become invalid. This also affects serialization of QDateTimes with
timezones.

Fixed by calling the name-only constructor first, which works (only) for
IANA standard timezones and leaves the QTimeZone invalid (isValid()
returns false) otherwise. In which case, we can call the many-argument
contructor to create a custom timezone with the same offset as the one
which was originally serialized.

[ChangeLog][QtCore][QTimeZone] Fixed sending IANA standard UTC-offset
QTimeZones through QDataStream, which previously came out invalid after
deserialization.
