e78e6c37ef g723_1: clip argument for 15-bit version of normalize_bits()
It expects maximum value to be 32767 but calculations in scale_vector()
which uses this function can give it ABS(-32768) which leads to wrong
result and thus clipping is needed.

110d015ad4 Revert "nuv: check per-frame header for validity."
The check is bogus since the nuv frameheader is already skipped
and the (decompressed) RTjpeg header is checked.

9829a81bcd ARM: vp56: allow inline asm to build with clang
The clang integrated assembler does not support pre-UAL syntax,
while gcc requires pre-UAL syntax for ARM code.  A patch[1] for
clang to support the old syntax as well has been ignored since
January.

This patch chooses the syntax appropriate for each compiler,
allowing both to build the code.  Notably, this change allows
building for iphone with the latest Apple Xcode update.

239fdf1b4a x86: build: replace mmx2 by mmxext
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

98d0d19208 lagarith: pad RGB buffer by 1 byte.
For left HFYU prediction, we predict from the buffer buf+1 using 8- or
16-byte reads. This means that aligning the buffer by 16 bytes is in
itself not sufficient, because if the width itself is 16- or 8-byte
aligned, the buffer will not be padded, and thus a read of size 16 at
buf+1 will overflow boundaries at the right edge. Padding the buffer by
1 byte is sufficient to not overflow its boundaries.

Fixes bug 342.

da6505ad2f dsputil: make add_hfyu_left_prediction_sse4() support unaligned src.
This makes add_hfyu_left_prediction_sse4() handle sources that are not
16-byte aligned in its own function rather than by proxying the call to
add_hfyu_left_prediction_ssse3(). This fixes a crash on Win64, since the
sse4 version clobberes xmm6, but the ssse3 version (which uses MMX regs)
does not restore it, thus leading to XMM clobbering and RSP being off.

Fixes bug 342.

8379ea5e9f vc1dec: Invoke edge_emulation regardless of MV precision
In VC-1 interlaced field pictures, chroma motion vectors can extend beyond
picture boundary even if luma vectors are bounded. The problem shows up
only for hpel interpolated MVs, and may be due to the way motion vectors
are scaled / cropped.

Thanks to Konstantin Shishkov for suggesting the fix. This fixes
long-known segfaults in MC-VC1.ts from videolan streams archive.
