QDateTime will attempt to convert unknown types of date to UTC time, which isn't
exactly a fast process. As we don't care about local timezones in the process of
sorting (as this is purely for ordering, not display to the end user), we can
force the dates to use UTC time, avoiding the unnecessary local timezone lookup.
This also adds a benchmark covering this case.
Benchmark results, Qt 5:
- before: 11, 489ms
- after: 273ms
Qt 4.8:
- before: 20, 848ms
- after: 278ms

Using the nullary version has the advantage that multiple calls
during a program run are much more efficient, since an inlined
atomic is used to store the result. It also ensures that
Q_DECLARE_METATYPE(T) has been used, whereas qRegisterMetaType<T>("T")
will happily register anything. So I've added the macro where it
was missing, or moved it to a central place when it existed
hidden.
In tst_qnetworkreply, this became a bit tricky, because a private
header is conditionally included, so moved the Q_DECLARE_METATYPE()
into a conditional section, too.

Store the signal index in QObjectPrivate::Connection, thereby making
it available in "implicit" disconnect contexts (i.e., receiver
deletion).
This change does not cause the size of QObjectPrivate::Connection
to grow (still 40 bytes on 32-bit Linux, 72 bytes on 64-bit Mac).
Valgrinding the new benchmark indicates that the percentage of the
time spent in the QObject destructor increased from 7.8% to 8.4%
on ia32, for that particular stress test; the increase is the
combined cost of calling metaObject(), QMetaObjectPrivate::signal(),
and disconnectNotify() for one connection. In practice, the measured
wallclock time increased by about 3ms for a 500ms run (which
repeatedly constructs, connects, and destroys an object).

qdatetime.h uses std::min/max and on Windows windows.h (or some subsequent
header file) may under certain circumstances define min/max as macros.
The easiest way to prevent the windows header files from doing that is to
define NOMINMAX in the place right before windows.h is included. The other
way is to define min and max to min/max themselves to prevent windows.h
from doing its evil thing.
If a user of Qt (WebKit in this case) chooses the approach of defining
min/max to themselves and then includes qdatetime.h, then a subsequent
inclusion of windows.h doesn't work because qdatetime.h undefines min/max.
We should not enforce the type of workaround needed, therefore this patch
removes the workaround from qdatetime.h and requires user code that
happens to include windows header files before qdatetime.h (seldom case)
to choose either workaround.

Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these
functions just to avoid an include, except to pay for it with worse runtime
performance.
On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15%
faster(!) than adding an additional call to qMemSet. The advantage on sizes
above that is unmeasurable.
For qMemCopy, the benefits are a little more modest: 16-7%.

QMap used to use a skiplist in Qt 4.x, which has variable
sized nodes and we can thus not optimise using custom
allocators.
The rewrite now uses a red-black tree, and all allocations
and tree operations happen in the cpp file. This will allow
us to introduce custom allocation schemes in later versions
of Qt.
Added some more tests and a benchmark. Memory consumption
of the new QMap implementation is pretty much the same as before.
Performance of insertion and lookup has increased by 10-30%. iteration
is slower, but still extremely fast and should not matter compared
to the work usually done when iterating.
