I actually found a few functions that were not even implemented, only
declared. Those should obviously not be in the header file. I've also
removed a few functions not in use / not belonging to QWidgetPrivate.

This patch cleans up several things, like bit fields that are
interleaved with with other variables, resulting in bits not being
packed properly.
Example: "uint a : 8; int c; uint b: 8;" -> "uint a : 8; uint b : 8; int c;"
In that case we'll use 12 bytes instead of 8 bytes.
I've also changed the order we declare certain variables to avoid
unnecessary gaps/padding on 64-bit architectures.
Example: "char *a; int c; char *b;" -> "char *a; char *b; int c;"
Pointers are 64-bit aligned, so padding appears between 'c' and 'b',
resulting in a total use of 24 bytes instead of 20 bytes.
...and since I anyways was moving the code around, I took the
opportunity to add some overall structure by first declaring
cross-platform functions/variables followed by platform specific
functions/variables. ...and it was kinda scary to actually be
able to see all the QStrings, pointers and whatnot we put into
QWidgetPrivate. I'm sure we can remove lots of stuff, but I'll do
that in a separate commit.
Quick numbers (X11/64 bit):
sizeof(QWidgetPrivate) == before: 472, after: 456
sizeof(QTLWExtra) == before: 112, after: 104
sizeof(QWExtra) == before: 152, after: 144

The reason is that we never applied the new max min values on the
native window itself. This patch does that, and also makes sure that
we do this on the appropriate times (window creation, etc)

QGLWidget does not support partial updates unless the context is
single buffered and auto-fill background is disabled. The problem
was that QPaintEvent::region() returned the requested update region
without taking into account the limitation of QGLWidget. If QGLWidget
doesn't support partial updates, it means everything has to be updated,
and QPaintEvent::region() must return the whole widget rect.
Auto test included.

This is not strange since we never did anything to limit a resize within
the max min boundries. This patch factores out the code that ensures
this into a private function that is called both as a reaction to a
resize event, but also if resize is done programatically.
