This reverts commit 62b5ef3cc1306e46a4042b14867f2f92d9a110f3.
The implementation of hfw from this patch is unfortunately not robust enough.
It doesn't manage correctly the constraints on the layouts and the cell spans.
It caused bad behaviour or regressions seen in tasks:
QTBUG-13547, QTBUG-13067, QTBUG-13549, and more

the problem was that the item is first painted at its default position,
then moved by the layout and finally repainted.
We now made sure the item is laid out before the first paint event
occurs.

When rasterization in the gray raster fails due to out of memory there
might already have been a number of spans flushed. To avoid flushing
these spans multiple times and thus getting overdraw artifacts we need
to keep track of how many spans to skip when we redo the rasterization.

TPos needs to be 32-bit, not 64-bit. QT_FT_Pos being 64-bit caused
sizeof(TWorker) + sizeof(TCell) in qgrayraster.c to exceed 4096, which
is the MINIMUM_POOL_SIZE, leading to rendering errors in certain cases.

Change c46688b8a88da made us use m_curve_threshold for both
QBezier::shifted and QBezier::toPolygon, and adjusted the threshold
dynamically based on the painter scale. Since the threshold in shifted
was already relative to the pen width, it is independent from the
painter scale. Instead, we need to set a separate threshold for dashing.
Also, in several places we were calling setCurveThresholdForTransform
with the painter matrix even though we were transforming the points into
device coordinate space before stroking.

We made a mistake of trying to make use of the texture_from_pixmap
extension by default when binding textures in Qt. The extension
have several limitation and using it produces crashes with certain
drivers/graphic card combos, but we can't change this now since
it will break existing apps using well behaved drivers.
We'll fix this for 4.8 with either a QGL::BindOption or configure
flag.
Revert "Don't try to use the texture_from_pixmap extension in
GL on desktop/X11."

Set various pragmas and defines to tune the hybrid allocator.
Performance test was the time takes to allocate or deallocate as
appropriate 1,000,000 times from a set of 100,000 pointers, selected at
random, with sizes generated randomly with min 2, max 5960, avg 46.
The function was exp(8 - log(2 + rand(0..1023))) * rand(1 or 4).
The following parameters were chosen:
* pragma arm, for ~1.2%
* pragma Otime, for ~3%
* pragma O2, already the compiler default, just to be sure
* all possible slab sizes enabled, for ~1%
NB Disabling BTrace would also gain ~1.5%, but that seems like a bad
thing to do. Not done.

newallocator_hook.cpp had #include <u32std.h> for the definition of
SStdEpocThreadCreateInfo. This header is not available in earlier S60
platforms. But we do not need the full definition of
SStdEpocThreadCreateInfo, so a forward declaration is used instead.

The allocator code copied from 10.1 would have no default value set for
KHeapShrinkHysRatio, since it's no longer a patchable constant. This
change gives it a value of 0x800, to be tuned for performance.
