03dc2b2e82 QSystemTrayIcon: handle submenus correctly
This fixes a bug when submenus are shown as simple actions when
a platform system tray icon is used.

To correctly handle submenus, we need to set platform menus on
all submenus, and only then on a parent menu.

06602f9c96 Android: Don't force-include android-9 headers in qpa plugin
When we supported platforms < android-9, we needed to include
some headers which were introduced in android-9 to compile the
QPA plugin. This is no longer needed, and also creates problems
when you pick e.g. android-21 as your platform, since some
definitions (specifically fd_set) are different in the two sets
of headers, giving us an undefined reference to
QEventDispatcherUNIX::select().

586fd04234 OS X/iOS: Fix stretched font rendering
Setting the stretch of a QFont did not work correctly on OS X or
iOS.

Two things are needed to make it work: First of all, we need to
properly set the transform when creating the CTFont.

In addition, we need to manually scale the advances, as
CTRunGetPositions() does not do this for us. On OS X 10.6, however,
there was a regression and CTRunGetPositions() would return scaled
positions, so we exclude the step to scale the advances on this
particular version.

This is an adaptation of bc25cfdd65452efa226cbd544c9ae9803eb6748a
in Qt 4.

[ChangeLog][QtGui][OS X/iOS] Fixed a bug when rendering fonts that
were set to be stretched.

2ecde56f65 QSortFilterProxyModel: fix a regression
bec1854cc0 introduced a regression:
when sorting a tree model, children items would not follow the sorted
parents any more (they wouldn't be remapped correctly), resulting
in crashes.

So, the fix needs more reasoning; let's revert the fix,
but leave  the original test around for any subsequent attempt, and
introduce a new test which looks for the right behavior when
sorting trees.

This commit partially reverts bec1854cc0.

a4c837b3a1 Fix QUdpSocket's emission of readyRead()
The documentation says that QUdpSocket emits readyRead() only for one
datagram and that if you don't read it, the class will not emit again.
That should be implemented by disabling of the socket notifier once we
have the datagram already read, but was broken.

In turn, that breakage caused a live-lock of the event loop: since we
didn't disable the notifier nor read the pending datagram, the event
loop would fire every time for the same datagram.

The re-enabling of the notifier was already working.

91d6aafad4 Windows: avoid generating exposes on plain moves
The fake expose generation for shrunk windows is causing
side effects with desktop GL: it will generate expose events
even when only moving the window. This is bad. So change the
condition to look for shrinking and do nothing if the size is
same as before.

This is reported to cause perf issues with e.g. QOpenGLWindow
or similar where an expose does an immediate repaint (potentially
with block swap).

730d07df83 Account for pixmap's device pixel ratio when calculating the label size
When determining the size of the QPushButton's label then the device
pixel ratio of the pixmap used to represent the icon needs to be taken
into consideration so it is rendered correctly.

17cce24648 Only call ShowWindow() once when going from FullScreen to Maximized
Since going from FullScreen to Maximized is taken care of inside the
FullScreen block then we don't want to call ShowWindow() again in the
Maximized block. Therefore the Maximized block is moved so it is only
invoked if it is not coming or going to fullscreen.

As the minimized case is not accounted for in FullScreen that is left as
is in its own if block.

b69c2e86de QFreeList: fix undefined behavior
Signed integer overflow is undefined behavior ([expr]/4),
but unsigned arithmetic doesn't overflow, so isn't
([basic.fundamental]/4, footnote there).

So, use unsigned arithmetic for the loop-around serial
number generation in incrementserial(). While we're at
it, also use it for the masking operation in the same
function.

Found by UBSan.

62a96dbb53 QTextFormat: fix undefined behavior
Left-shifting of negative values is undefined ([expr.shift]/2).

Since hashValue is a uint already, rectify by casting it->key to
uint prior to shifting.

390ea21873 QByteArrayMatcher: fix undefined shift
The REHASH macro is used in qFindByteArray() with a char argument.
Applying the shift operator promotes (a) to int. The check in
REHASH, however, checks for the shift being permissible for
_unsigned_ ints.

Since hashHaystack is a uint, too, rectify by casting (a) to
uint prior to shifting.

Found by UBSan:

  src/corelib/tools/qbytearraymatcher.cpp:314:72: runtime error: left shift of 34 by 30 places cannot be represented in type 'int'
