The logic is now mostly handled in QGuiApplication, with QApplication
only dealing with the widget-specific palettes and interaction between
the style and the palette.
The application now picks up changes to the platform theme and will
re-resolve the current application palette appropriately. This also
works even if an explicit application palette has been set, in which
case any missing roles are filled in by the theme.
The palette can now also be reset back to the default application
palette that's fully based on the theme, by passing in the default
constructed palette (or any palette that doesn't have any roles set).
This is also correctly reflected in the Qt::AA_SetPalette attribute.
Conceptually this means QGuiApplication and QApplication follow the
same behavior as QWidget, where the palette falls back to a base or
inherited palette for roles that are not set, in this case the theme.
Behavior-wise this means that the default application palette of the
application does not have any roles set, but clients should not have
relied on this, nor does QWidget rely on that internally.
It also means that setting a palette on the application and then
getting it back again will not produce the same palette as set,
since the palette was resolved against the theme in the meantime.
This is the same behavior as for QWidget, and although it's a
behavior change it's one towards a more sane behavior, so we
accept it.
[ChangeLog] Application palettes are now resolved against the platform's
theme palette, the same way widget palettes are resolved against their
parents, and the application palette. This means the application palette
reflected through QGuiApplication::palette() may not be exactly the same
palette as set via QGuiApplication::setPalette().

...but keep support for deserializing for all older versions in order to play
nice with existing .qsb files.
The usage of binary JSON and then CBOR is a historical artifact: relying
on the QJsonDocument (which we generate for purposes unrelated to binary
serialization) was a convenient shortcut. However, writing to and
reading from a QDataStream instead (which QShader already does) is trivial.
In order not to be limited by potential CBOR requirements in the future,
take it all into our own hands.
Extend the qshader autotest accordingly.

The new float16texture_with_compute manual test demonstrates a case
that was not handled correctly before: multiple dispatch() calls in
a row storing to and then loading from the same subresource(s).
Without the appropriate barriers subtle data corruption issues appear.
For Vulkan this also adds better batching for image/buffer barriers when
using deferred recording.
Also, for OpenGL this fixes the case of updating a buffer or rendering into
a texture and then using it for load/store in a compute pass (previously this
also lacked an appropriate glMemoryBarrier).

Use QStringIterator rather than indexed loops. This fixes handling of
non-BMP code points (which may be lower or uppercase, see the test).
Change also the semantics of the functions, adopting Unicode §3.13
definitions: a string is lowercase/uppercase if it's equal to its
own toLower/toUpper folding.
As a side effect, empty strings are now correctly reported to be
lowercase AND uppercase.
[ChangeLog][Important Behavior Changes] The semantics of
QString::isLower() and QString::isUpper() have been changed to match the
Unicode specification. Now lowercase (resp. uppercase) strings are
allowed to contain any character; a string is considered lowercase
(resp. uppercase) if it's equal to its own toLower() (resp. toUpper())
folding. Previously, a non-letter character would make the string not
lowercase nor uppercase, and the mere presence of an uppercase (resp.
lowercase) letter would make isLower() (resp. isUpper()) return false,
even if the letter wouldn't change under case folding. As a
consequence, now empty strings are lowercase and uppercase.
[ChangeLog][QtCore][QString] Fixed a number of bugs of
QString::isLower() and QString::isUpper(). Empty strings are now
correctly reported to be lowercase (resp. uppercase), and strings
containing code points outside the BMP are now correctly handled.
Note that the behavior of these functions has also been changed.

Linux 5.2 added the CLONE_PIDFD flag to the clone(2) system call. Linux
5.3 also added the clone3(2) system call, which allows both CLONE_PIDFD
and CLONE_PARENT_SETTID, which we could use but don't really need.
Unfortunately, 5.2 missed one crucial and one convenient change. Without
the P_PIDFD support in waitid(2), we would need to either remember the
PID of the child process or obtain it from /proc. But without support
for polling on pidfds, we can't find out when the child process
exited. Support for the latter was added in 5.3, which would be
sufficient for us, but it's not easy to detect it at runtime. The
support is also being backported to Android's 4.9 kernel[1], so we can't
do version checks, only functionality.
This commit relies on waitid(2) support, which was the last to be added
and is fortunately the easiest to detect. If it's present, we assume the
whole series is present and use pidfds.
