5a57ddebf5 Fix tst_QDialog::deleteInExec() crash on Mac OS X
When destroying a window immediately after showing it, we can sometimes
provoke a crash in Cocoa after the show-window-animation has finished
(which appears to assume that the window's view will always be valid).
Prevent the crash by not removing the view from the window. When
recreating a window, we explicitly release the old window, but we do not
release the view, so we can freely add it to the new window (i.e. this
does not introduce new bugs related to recreating the platform window).

f0c36dd03c Introduce fallback for general cross compilation
The current approach of forcing people to pass the fully qualified prefix
of their toolchain to the configure script is verbose and something of a
chore for people who use the same toolchain to target several devices.

This allows you to set a single toolchain for use with all Qt targets via:

qmake -set CROSS_COMPILE foo

You can still explicitly override this toolchain, as originally mandated,
with the configure time device-option arguments.

Growth computations are deferred to QArrayData::allocate, except in the
case of realloc as that functionality is currently lacking in
QArrayData. Since that sits in library code, anyway, it can be changed
later to use a future QArrayData::reallocate.

As it is, reallocData is becoming a model for QArrayData::reallocate
and what it can offer to containers of POD/movable types.

For the time being QByteArrayData keeps its independent existence, for

Extra braces can then be added to the macros.

With respect to source compatibility, the only concern is with other
modules, as QByteArrayData has already changed in incompatible ways with
Qt 4.x

2ac4c463af Make QByteArray and QString keep track of terminating null
In conceptual terms, this change increments the Data::alloc member by
one for all strings allocated and maintained by these classes. Instances
initialized with fromRawData retain 0 as the member value, so they are
treated as immutable.

This brings QByteArray and QString closer to QVector, making it possible
for them to reference and share the same data in memory, in the future.
It also brings them closer to QArrayData.

In practical terms all comparisons to the alloc member were changed to
take into account that it also tracks the terminating null character.

Aside from the increment in the alloc member, there should be no user
visible changes.

e02a144a3c Finish cleaning up com.trolltech -> org.qtproject in QtDBus
Lots of uses of the annotations and error names, plus a bunch of local
unit test names (including one file that had to be renamed).

The meta object generator is updated to support both the old and new
names. That means some references to com.trolltech *must* remain in the
source code.

65e75acd05 Update the error codes in QtDBus
Change the old com.trolltech ones to org.qtproject and introduce Use
the alternate domain name for the Qt Project because the dash
character is not valid in interface and error names.

51fecf80b7 Mark tst_qabstractitemmodel as insignificant after QHash randomization
The testChildrenLayoutsChanged fails randomly. This happens rarely,
f.i. wasn't spotted by CI when QHash randomization itself was merged;
but is indeed reproducible by running the test a few times in a row.

This is now blocking api_merges integration, and I have no idea
how to fix it.

This patch marks the test as insignificant for now (the bug
tracking this test failure is QTBUG-25325), and switches the failing
tests from QVERIFY(a == b) to a proper QCOMPARE (so that the
expected values do show up in the build logs).

83fc52e3b4 widgets: Fix painting to a fully transparent top level widget
QWS used to have a line to change the composite mode from SourceOver
to Source for the top level widget. This wasn't used with QPA and I
removed the internal DontSetCompositionMode in qtbase. It turns out that
the QWS way is the most efficient one to initialize the background of
the widget.

The alternative is to have the QPlatformBackingStore::beginPaint
always clear the entire to be painted area and then paint the background
of the widget. The difference of painting each pixel once or twice is
noticable on embedded platforms and in the range of one to two fps.

Reproduce the issue with:
echo "QWidget {background: transparent}" > style.css
./examples/widgets/wiggly/wiggly -stylesheet style.css
