- Replace Q[TRY]_VERIFY(pointer == 0) by Q[TRY]_VERIFY(!pointer).
- Replace Q[TRY]_VERIFY(smartPointer == 0) by
Q[TRY]_VERIFY(smartPointer.isNull()).
- Replace Q[TRY]_VERIFY(a == b) by Q[TRY]_COMPARE(a, b) and
add casts where necessary. The values will then be logged
should a test fail.
Tests from corelib/tools were omitted in this change.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

This is extremely useful, since the most common action after a failed
compare-and-swap is to loop around, trying again with the current
value as found in memory.
Code currently written as:
do {
Type value = atomic.load();
...
} while (!atomic.testAndSetRelaxed(value, desired));
Becomes:
Type value = atomic.load();
do {
...
} while (!atomic.testAndSetRelaxed(value, desired, value));
In most CPU architectures, the value that was found in memory is known
to the compare-and-swap code, so this is more efficient than the
previous code. In architectures where the value is not known, the new
code is no worse than before.
The implementation sometimes modified an existing function, sometimes
it added a new one, depending on whether more registers were needed in
the assembly (like ARMv6-7), the code became more complex (ARMv5), the
optimizer failed (C++11), or it was just plain equivalent (MIPS).

Qt 5.0 beta requires changing the default to the 5.0 API, disabling
the deprecated code. However, tests should test (and often do) the
compatibility API too, so turn it back on.

This is a source incompatible change. There is concern that the
convenience of the implicit cast and assignment operators can lead to
misuse. Several commits have already been done that remove excess use
of the implicit cast, which is a *volatile* read every time it's used.
Users of the QAtomic* API should have to think about when they are
loading the value, and if they do or don't need the acquire memory
barrier on load. The code that people would write using this API is
meant to be multi-threaded, concurrent, and correct. The API should not
allow them to inadvertently, possibly unknowingly, shoot themselves
in the foot.

Use QAtomic*::load() and ::store() instead of the deprecated
cast, assignment, and comparison operators. These will be removed
in the near future.
The tests for these particular operators have not been changed,
though, as the change to remove the operators will also remove
the respective tests.
