c2b7841843 Finally fix crash in inplace-modified data-constructed images
Avoid all inplace modification of images using external data
buffers. Since the QImage methods are documented to create a
(modified) copy, there is afterwards no API requirement on the
lifetime of the data buffer.

This patch supersedes 509bc7e59c

a4e2f2e687 Fix possible crash in QImage::pixel()
QImage::pixel() assumed that the color table was valid
for the values in the bitmap. This was always wrong
for indexed images with explicit no color table set and
was wrong for mono images that were constructed from
preexisting data.

For mono images, we default to a black/white color table,
like we do when constructing with uninitialized data.

For indexed image, we always default to no color table,
but instead of crashing in pixel(), we warn and return
an undefined value.

[ChangeLog][QtGui][Image] Fixed possible crash in QImage::pixel()
for mono or indexed images.

d290424f2a NEON optimized bilinear sampling
Adds NEON version of interpolate_4_pixels used by smooth upscaling, and
bilinear sampling.

The SSE2 version is reordered to match the NEON version so they have
the same order of operations and a faster version that loads directly
into vector registers.

Testing is extended so we have a test of smoothness that can catch more
possible mistakes.

509bc7e59c Fix another crash when converting format of buffer-created QImage
This continues 68762151db

When doing format conversion, the optimized inplace codepath did not
check if the image data was external, i.e. if the QImage had been
created by the constructor taking an existing external buffer.

The previous commit fixed the readonly case. But in the case of the
QImage constructor taking non-const uchar*, data will be read-write,
but still external. This would of course crash if the converter tries
to realloc it.

d84a6eab51 Add Grayscale8 and Alpha8 formats to QImage and drawing
Extend the QImage format with two 8-bit grayscale and alpha formats.
These formats have the advantage over Indexed8 that they have simpler
conversion and can be rendered to by the raster engine.

[ChangeLog][QtGui][QImage] Added support grayscale and alpha 8-bit
formats which can also be rendered to.

2431bf1b20 QPixelFormat: don't inherit it
Instead of abusing inheritance to provide convenience constructors,
use simple inline constructor functions. The name got a lower-case
q to indicate a free function. The usual fromXYZ() static methods
were deemed not fitting in this case in the initial round of review,
since they implied some kind of conversion while these functions are
simply constructors of formsts, which contain no data.

This also solves the problem that some of these ctors could have been
called with just one argument and were therefore candidates for hidden
QPixelFormat temporary injection.

QPixelFormatRgb was renamed to qPixelFormatRgba to explain the third
argument at the call site better.

There seem to be no users of this class in qt5.git at this time.

d8dc664b94 Ensure valid data after QImage::invertPixels
QImage::invertPixels may produce invalid data after inversions of
images with premultiplied alpha, because the inverted colors will be
larger than the alpha.

This patch converts any image with a premultiplied alpha channel to
ARGB32 before inverting the pixels, and then back to the original
format after the inversion.

Support is added for correct inversion of RGBA8888 and RGB30 formats.
