a5febadac5 QString(Ref): make toLatin1()/toLocal8Bit() null handling consistent
Systematic testing in tst_QStringApiSymmetry revealed a bug in
QStringRef::toLatin1(): a null input did not result in a null output,
but an empty one. This is fixed, for consistency with
QString::toLatin1(), and QString(Ref)::toUtf8(), which behaved
correctly already.

The same bug was found in QString(Ref)::toLocal8Bit(), which is
particularly hideous, as it's documented to fall back to toLatin1(),
which preserves null inputs. Fixed, too.

[ChangeLog][QtCore][QString] toLocal8Bit() now preserves nullness of
the input QString (outputs null QByteArray).

[ChangeLog][QtCore][QStringRef] toLocal8Bit() and toLatin1() now
preserve nullness of the input QStringRef (output null QByteArrays).

2aec5c9b34 Package transient zone setting in test to ensure restore on fail
tst_QDateTime::operator_insert_extract() was setting the time-zone and
taking care to restore it at the end of the test; however, if the test
were to fail, the restore would be skipped.  Package the zone-setting
and restore in a class instance, so that premature return can't bypass
the restore.

b4689401a5 tst_QThreadPool: don't deadlock when a cancel() test fails
We keep the runnables from finishing by having them block
on a QSemaphore::acquire() call inside run().

If we fail a test that precedes the call to sem.release()
further into the test, the early return will cause the
thread pool to be destroyed, which will then attempt to
wait for the runnables to finished, which, in turn wait
for the semaphore to be released.

-> dead lock

Fix by introducing a RAII object to release the semaphore
with a sufficiently large number to unblock all runnables.
That number will in some situations be too large, but that
does not matter.

does will vary from run to run.

9db8c171e7 Fix QLibrary::isLibrary on Apple platforms
Add proper support for 'so' and 'bundle' suffixes.  Qt wrongly assumes
.so libraries are not versioned on Apple platforms, which is
wrong. Also, the shared library .bundle which is what Apple recommends
instead of .so, are also versioned (not to be confound with the
different Core Foundation bundles, which are directory hierarchy).

For more info, see http://docstore.mik.ua/orelly/unix3/mac/ch05_03.htm.
Especially the part that reads:

"Loadable modules, called bundles in Mac OS X, have the file type
MH_BUNDLE. Most Unix-based software ports usually produce bundles with a
.so extension, for the sake of consistency across platforms. Although
Apple recommends giving bundles a .bundle extension, it isn't
mandatory."

9e5e30fa13 QStringMatcher: fix setCaseSensitivity() on a non-QString-backed matcher
When a non-QString-backed mode (via the (QChar*, int) ctor) was added
for Qt 4.5, the author forgot to adjust the setCaseSensitivity()
function.  It still uses q_pattern instead of (p.uc, p.len) as the
pattern for which to create the skip-table. Since there is no
setPattern() overload for this mode, the correctness of the matcher is
not harmed by this, but its performance degrades to that of a linear
scan: the skip-table, being filled from an empty pattern, will be
all-zeros, sending bm_find() into the 'possible match' case at every
character.

Since matching is still correct, but slow, it's not possible to write
a test for this. I did, however, leave my attempts in the auto-test,
for when we add QStringView overloads of setPattern() which will then
be able to expose the bug.

578154c47d tst_QPauseAnimation: Use QTRY_COMPARE for checking the stopped state
Use QTRY_COMPARE with a timeout to check for the stopped state
unless BAD_TIMER_RESOLUTION is defined.
This speeds up the test by 1s and prints diagnostic information
should an interval be too short (as seems to be the case on macOS,
currently).

da0241a2e7 Make variant selection possible if base is missing
[ChangeLog][QtCore][QFileSelector] Removed the requirement for an unused
default base file in case you want to load only a variant.

When the base file (e.g. /image.jpg) was missing, no selectors were
considered and it was not possible to load variants of this file (e.g.
/+android/image.jpg, /+android/+tablet/image.jpg) without specifying the
directory as well.

As a work around, one previously had to place a default file in
the base location, which is undesirable in some cases because:
1. The extra file consumes unnecessary space.
2. It is impossible to encapsulate platform-specific implementation
   details by hiding files in a subdirectory.

3af5cab054 Long live QStaticByteArrayMatcher!
This is a version of QByteArrayMatcher that calculates the
Boyer-Moore skip table at compile-time instead of at run-time,
making this class more generally applicable than QByteArray-
Matcher itself, at least for statically-known strings.

The compile-time part requires C++14 constexpr support, but
the class should compile and work even in C++98 mode, just
with runtime initialization of the skip-table.

While touching tst_qbytearraymatcher, clean up the static
global QByteArrayMatchers there and add tests with needles
longer than 255 characters for QByteArrayMatcher, too.

[ChangeLog][QtCore] Added QStaticByteArrayMatcher.

5a1b4832a2 Adapt to the C++ SIC introduced by P0021: noexcept overloading
C++17 adopts P0021R1[1], which makes noexcept be part of the function
pointer's type and thus be overloadable. It contains some provisions for
allowing a noexcept function pointer to cast implicitly to a non-
noexcept function pointer, but that fails in the presence of templates
and additional overloads that could match the type in question.

Fortunately, the paper proposed a test macro, so we can change our
sources now and be compatible with both C++14 and C++17 rules.

This first failed with Clang 4.0 trunk. This source incompatibility is
not our fault, it's the language's doing.

6255cb893d Remove qtypetraits.h's contents altogether
So that QFlags can use an (un)signed int matching the
underlying type as identified by the compiler and not by us.

Requires fixing a few warnings about sign conversion due to
QFlags misusages in qtbase that were either plain wrong, or
were relying on the enum being backed by an (un)signed int
when it wasn't.

Keep qtypetraits.h in the source tree in order to prevent
source breaks if some downstream #includes it (note however
that it did not contain any public API).

2b928ef6f9 Provide sensible defaults for QCoreApplication::applicationVersion
[ChangeLog][QtCore] QCoreApplication::applicationVersion now defaults to
an appropriate platform-specific value. On Windows, it defaults to the
PRODUCTVERSION parameter of the VERSIONINFO resource for classic desktop
apps, and the version attribute of the application package manifest for
Univeral Windows Platform apps. On Apple Platforms (macOS, iOS, tvOS,
watchOS), it defaults to the CFBundleVersion property of the information
property list (Info.plist) file. On Android, it defaults to the
android:versionName attribute of the AndroidManifest.xml manifest
element. On other platforms, the default remains an empty string.

4b4bd6ab98 Simplify fileTimeToQDateTime() by having it return a UTC time
This avoids so many complications.  The prior code, using
SystemTimeToTzSpecificLocalTime(), lead to unhelpful results when the
QDateTime() implementation used MS-POSIX's defective mktime().
Although SystemTimeToTzSpecificLocalTime() is actually more correct,
we were getting inconsistent results by mixing the two: and
eliminating the use of mktime() turns out to be decidedly tricky.  So,
to avoid inconsistency, stick with a UTC time (which is what FILETIME
is defined as).  Change QFileInfo's methods to explicitly convert
.toLocalTime() where appropriate and document that these methods do
indeed return local time (as we conjecture has been taken for granted
by callers).

Also added a regression test for the reported case of this going
wrong.  A time-stamp from before Russia's (permanent, not DST) change
of TZ could end up inconsistently handled between file-system
meta-data and raw date-time APIs, due to cross-talk between different
MS-Win time APIs.

[ChangeLog][QtCore][QFileInfo] Made sure that all file lifecycle times
are in local time. This was probably true before, but is now explicit.
