00e8f044e1 QWidget: document that a widget might only get a mouseDoubleClickEvent
If two widgets are on top of each other, and the top widget disappears
in response to a press or release that is followed by a double click,
then the widget at the bottom only receives the double click event.

This is a sequence of events that the application developer that choses
to build such a UI has to take care of.

c962c77044 CoreText: Warn the user when family alias lookup slows down the application
If the user specifies a font family in their application that doesn't
exist in the system, or one that uses the localized family name, we
will end up resolving the family alias for all fonts in the system,
which typically adds 600-800ms of startup time. Let the user know
when this happens.

a6ffdbe30c QTextCodec: try to work around an ICC 19 bug
ICC 19 barfs on the TextCodecsMutexLocker class because it doesn't
have a user-provided default ctor:

  ../../corelib/codecs/qtextcodec.cpp(543): error #854: const variable locker requires an initializer -- class TextCodecsMutexLocker has no user-provided default constructor
  [...]

But the class doesn't have members that would delete the
implictly-declared default ctor, so no user-provided default ctor
should be necessary:

The only member is the result of qt_unique_lock(), which is
std::unique_lock, which does have a default ctor.

We conclude that this is a compiler bug, and work around it with the
introduction of a user-provided default ctor.

Fix brace placement as a drive-by.

0118e2e915 Include likely-adjusted uiLanguages for the system locale
QLocale::uiLanguages() on the system locale uses whatever the system
locale's query(QSystemLocale::UILanguages,...) returns. On Android,
this is just a list of locales. However, for non-system locales, we
also include some results of removing likely sub-tags from the locale
name, where equivalent. Thus zh-CN would also get zh and zh-Hans-CN
added to it; however, if the system locale is zh-Hans-CN, the shorter
forms are omitted. So post-process the system locale list in the same
way, albeit tweaked to avoid duplicates and rearranged so that we can
insert likely-adjusted entries between what they adjust and what
followed it.

Added QLocalePrivate::rawName() in the process, since it looks likely
to be useful in other contexts (and I needed its value): it just joins
such tags as are non-Any. This, however, uses QByteArrayList, so added
that (it's small) to the bootstrap library and qmake.

This follows up on commit 8796e3016f.

[ChangeLog][QtCore][QLocale] The system locale's UI languages list now
includes, as for that of an ordinary locale, the results of adding
likely sub-tags from each locale name, and of removing some, where
this doesn't change which locale is specified. This gives searches for
translation files a better chance of finding a suitable file.

91a869671e CMake: generate moc files for headers using Q_NAMESPACE_EXPORT too

b4efdd3769 Reorganise the qfloat16 auto-test
Its limits() test was rather large and had some overlap with an older
qNan() test, that needed some clean-up (it combined qfloat16 values
with double and float values in ways that caused qfloat16 to be
promoted to another type, so we weren't testing qfloat16).

Renamed the qNan() test to qNaN(), separated out the parts of it that
actually tested infinity. Moved various parts of limits() to these and
rationalised the result. Split out a properties() test from limits()
for the properties of the qfloat16 type that are supplied by its
numeric_limits. Split out a data-driven finite() test to cover some
repeated code that was in limits() and extended it to test more
values. Added more tests of isNormal().

Fixed my earlier UK-ish spelling of "optimise", in the process, and
identify the processor rather than the virtualization as the context
where the compiler errs.

2e068c7f2a Add TriangleFan pipeline topology
Triangle fan drawing is only supported on some platforms. The feature
flag QRhi::TriangleFanTopology is set accordingly.

In general, TriangleStrip topology will be more efficient on most GPUs.
However, if polygon data is already stored as triangle fans, the CPU
savings may be more significant.

f1c7814a55 rhi: Remove QVectors from the data description structs as well
As usual, keep some QVector overloads around to allow Qt Quick to compile.

Color attachments and vertex input bindings get an at(index) type of
accessor, unlike any other of similar lists. This is because there the
index is significant, and sequential iteration is not the only type of
operation that is performed. Sometimes a lookup based on an index will
be needed as well.

1a8f4a3c8f GSSAPI: strengthen configure test and make it a library
This way we can actually filter out times in sitatuations where it
proved to not be available and as a library we can simply "use" it.

Added in the pkgConfig source as well to make sure we can pick it up
on systems where it has a different name.
