Bradley T. Hughes 88da8b4878 QMutex: de-inline lock(), unlock(), and tryLock()
See the discussion of this topic on the mailing list:
http://lists.qt-project.org/pipermail/development/2012-May/003943.html

The consensus is to not have these methods have inline code to actually
acquire the lock (i.e. no atomic test-and-set or similar). QBasicMutex
is unchanged, and continues to have inlined lock(), tryLock(), and
unlock(). QMutexLocker has been changed to always call QMutex::lock()
(even though the constructor takes a QBasicMutex parameter).

Casper van Donderen 0bc02fd0d6 Doc: Prepare for building modular QtCore docs.
This change fixes most qdoc errors in QtCore. There are about 900 left.
The main thing this change does is moving documentation from qtcore from
/doc/src to /src/corelib/doc.
Other issues resolved are mis-use of qdoc commands.

Jason McDonald 5635823e17 Remove "All rights reserved" line from license headers.
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.

Gunnar Sletta 4ecf82795d Remove use of QT_MODULE from library
These defines were there to aid in the commercial
licensing scheme we used long ago, and are no longer needed.

Keep a QT_MODULE(x) define so other modules continue compiling.

Because we use d as a local variable.
We used this->d to refer it, but this can be confusing to have twice the same

Thiago Macieira 5bfeab8749 Make all uses of QBasicAtomicInt and Pointer use load() and store()
Most of these changes are search-and-replace of d->ref ==, d->ref !=
and d->ref =.

The QBasicAtomicPointer in QObjectPrivate::Connection didn't need to
be basic, so I made it QAtomicPointer.

Olivier Goffart 86a237929e QMutex is now just a pointer
And added a POD QBasicMutex. (QBasicMutex* can safely be
static_cast'ed to QMutex*)

The d pointer is not anymore always a QMutexPrivate.

If d == 0x0: the mutex is unlocked
If d == 0x1: the mutex is locked, uncontended

On linux:
if d == 0x3: the mutex is locked contended, waiting on a futex
If d is a pointer, it is a recursive mutex.

On non-linux platforms:
When a thread tries to lock a mutex for which d == 0x1, it will try to
assing it a QMutexPrivated (allocated from a freelist) in order to wait
for it.
