Because the order of evaluation of subexpressions is undefined, two
get_bits() calls may not be part of the same expression. In this
specific case, using get_bits_long() is simpler.
This fixes msmpeg4v1 decoding with armcc.

Compilers may assume a pointer has natural alignment, even if it was
assigned from a pointer type with weaker alignment requirements. It
is thus not safe to assign a possibly unaligned value to a pointer,
regardless of how it is subsequently dereferenced.

link rather than avfilter_default_get_video_buffer().
This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").
In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.

This performs quite a bit better than the current 3GPP-inspired window decision
on all the samples I have tested. On the castanets.wav sample it performs very
similar to iTunes window selection, and seems to perform better than Nero.
On fatboy.wav, it seems to perform at least as good as iTunes, if not better.
Nero performs horribly on this sample.

This allows cleaner implementation of other psymodels using the existing
structs. It also will make it easier to interchange individual parts of
the psymodel to create hybrid models.

instead of current "make output file of size less than ss".
Also use it to make MP3 tests more readable (using -fs xxx where xxx is
the requested output size, not something slightly lower).

This is to avoid split asm sections that attempt to preserve some
registers between sections.

since all of it ends up in a single 32-bit pixel.
This seems likely to be wrong though, since it is different
from the 15 and 16 bit modes and might explain the half-width
issue for 24 bit truemotion.

BGR32 and not BGR24, do not swap red and blue on big-endian
for this format as well.
