QtCore has a few headers that, though public, aren't meant to be
included directly. Those are the atomic headers, the three _impl.h
headers and qt_windows.h.
QtGui includes two OpenGL headers that don't compile on their own.
Other libraries should not have headers like that (but they do,
something we need to fix eventually).

The macro was made empty in ba3dc5f3b56d1fab6fe37fe7ae08096d7dc68bcb

This allows one to write code that depends on these values at

Actually, only the "new" atomics are marked. The old implementation,
based on qoldbasicatomic.h is unchanged, but should still work without a
problem.
The following configurations were tested and do work:
- x86 64-bit
- x86 32-bit
- generic GCC
- generic C++11 std::atomic
- bootstrap
- ARMv6 and 7
- MIPS
- MSVC 2010 32-bit
- MSVC 2010 64-bit
The only two configurations untested are IA-64 and ARMv5. Except for
MSVC, all configurations were tested with GCC 4.6 (MIPS and ARM) and 4.7
(x86 and generics).

This is so we can insert valgrind (helgrind) annotation macros. They
require the actual address of the variable to work.

Most of these headers are either forwarding headers, or we explicitly
stop syncqt so that it doesn't generate class includes for the atomic
implementation. Either way, syncqt doesn't see the QT_END_* (and
sometimes not QT_BEGIN_*), which this commit fixes.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

The implementation is divided in two files, as it used to be in the
previous implementation: one for ARMv5, one for ARMv6 and up.
For the ARMv5 implementation:
Drop the non-Linux EABI version of the atomics, as it's not
ABI-compatible with the ARMv6 and ARMv7 implementations. This
means this ARMv5 implementation only works on Linux. If other
systems implement kernel helpers like Linux, they can be added
too.
We use the __kernel_cmpxchg located at 0xffff0fc0 to implement the
operations, except for fetchAndStore, for which we use the SWP
instruction.
Also introduce the use of __kernel_dmb (at 0xffff0fa0) for the
memory barrier. Now this code is SMP-safe even when built with
ARMv5.
The kernel cmpxchg helper was introduced in Linux 2.6.12, whereas
the dmb helper was introduced in 2.6.15. That means 2.6.15 is the
minimum version now.
For ARMv6 and up:
Introduce byte, half-word and doubleword atomics that work on
ARMv6K and up.
For ARMv6 specifically, the memory barrier instruction (DMB) isn't
present, so we need to accomplish the same with the MCR
coprocessor instruction.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
Qt Git wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:
http://qt.gitorious.org/qt/pages/GitIntroductionWithQt
If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.
