Some auto-tests render into a QPixmap and check the result against
QPixmap::grabWidget(). Change acc1a2bd5520369c made grabWidget() render
into a QImage to be able to preserve background transparency. Instead,
to avoid breaking various auto-tests, we can use a QPixmap and fill it
with transparent if the widget's isOpaque flag is not set.

Use a QImage initialized with transparent to prevent any translucent
parts of the widget to end up as garbage, and to ensure that the
resulting QPixmap ends up with an alpha format only when needed.

The decoding from image reader was assuming the image reader do not
keep the image internally. This is not true for the GIF plugins because
the previous image can be used to compose the current image.
This was causing crash on ARM because the 16 bits color depth causes
the image memory to be reduce by half. When the plugin was accessing
the memory, it assumes the images has not changed and is on 32 bits.
This patch disable the in-place conversion if a detach is required.
Regular conversion is the correct solution in this case, and it can
also be made faster by converting while copying.

A regression from 4.6.x. This is an X11-only problem caused by the
separate masks that an X11 QPixmap can contain. These masks we're not
taken into account when a number optimizations were done for 4.7.
Introduction of the texture-from-pixmap extension in 4.6 also broke
masked pixmaps under X11.

Change 2c8f9dee611 had an unwelcome side-effect and was reverted.
Since we do have the undocumented behavior that we scan for all possible
extensions when QPixmap is provided with a filename without extensions
we could not simply exit if the file did not exist. We now check if
there are extensions before doing so.

The commit 90642dd2b6b14c39cc6178f1161331895809b342 introduce a fast
way to convert from RGB888 to RGB32 with SSSE3.
This patch uses that function to do the color conversion when decoding
jpeg images.
The #defines for the SIMD extension have been moved to the common code
in order to be able to compile the jpeg handler directly in QtGui or
as a plugin.

Converting from RGB encoded on 24bits to RGB encoded on 32 bits is
quite inefficient.
This type of conversion is common for some image format.
The patch implement the conversion with SSSE3. This reduce by 3 the
number of instructions, pushing the bottleneck to memory bandwidth.
On Atom N450, the new benchmark is 40% faster for scanlines of
2000 pixels, 30% faster for scanlines of 32 pixels, and 15% slower
for small images (3 and 8px).

QSymbianBitmapDataAccess is used to provide access to the bitmap heap
in a manner that locks correctly on all platform versions. The
heapWasLocked variable was meant to protect against the case where
the heap is locked recursively. However, it failed to take into
account the case where the same QSymbianBitmapDataAccess object was
used to lock recursively. In this case the variable would be changed
to true on the second lock, which means that the lock would never be
released again.
This was fixed by making the access reference counted instead. Since
the bitmap heap lock is global, the refcount was made global as well.
