4c399dc82b Fix undefined expressions that use multiple calls to get_bits(). 
Because the order of evaluation of subexpressions is undefined, two
get_bits() calls may not be part of the same expression.

See also r24902.

b3c1652b82 msmpeg4v1: fix undefined behaviour in msmpeg4_decode_picture_header() 
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.

62147469da acenc: LAME-inspired window decision 
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.

af00dddeca aacenc: Rename Psy3gpp* structs to AacPsy* 
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.

2a86d4b905 The 24-bit ydt also should not depend on endianness, 
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.

8bdf11815c Fixed mpeg12 top field first flag value with field picture encoding. 
The relevent extract of the iso 13818-2 about the value of the syntaxical
element top_field_first of the Picture Coding Extension is:

"top_field_first -- The meaning of this element depends upon picture_structure,
progressive_sequence and repeat_first_field.
[...]
In a field picture top_field_first shall have the value '0', and the only field
output by the decoding process is the decoded field picture."

dd5f3238c1 imc: fix undefined float to int conversion 
Conversion of an out of range float to int is undefined.  Clipping to
the final range first avoids such problems.  This fixes decoding on
MIPS, which handles these conversions differently from many other CPUs.

This should reduce the size of builds with one of these derivatives but without
H.264 decoding itself.

6341838f3c Use word-writing instead of dword-writing (with two cached but otherwise 
unchanged bytes) in the horizontal simple loopfilter. This makes the filter
quite a bit faster in itself (~30 cycles less on Core1), probably mostly
because we don't need a complex 4x4 transpose, but only a simple byte
interleave. Also allows using pextrw on SSE4, which speeds up even more
(e.g. 25% faster on Core i7).

ef38842f0b VP8: smarter prefetching 
Don't prefetch reference frames that were used less than 1/32th of the time so
far in the frame.
This helps speed up to ~2% on videos that, in many frames, make near-zero
(but not entirely zero) use of golden and/or alt-refs.
This is a very common property of videos encoded by libvpx.

3fc548df28 Make ff_inverse stay with libavutil, and optional copy it to libavcodec. 
The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
to now the table was defined only in libavcodec.

After this change, the main copy of ff_inverse is part of libavutil (just
like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
available to libavcodec, to avoid the performance penalty of using an
external look up table.

Dynamic linking works, because the libraries are linked with -Bsymbolic, so
the local copy of the symbol has priority over the external; static linking
works because the table is on a standalone object file in both libraries,
so the linker is able to discard one of the two.

Tested on Linux/x86-64 and Mac OS X/x86-64.

6526976f0c Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than 
regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag,
FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that
have been checked specifically on such CPUs and are actually faster than
their MMX counterparts.

In addition, use this flag to enable particular VP8 and LPC SSE2 functions
that are faster than their MMX counterparts.

3facfc99da Change function prototypes for width=8 inner and mbedge loopfilter functions 
so that it does both U and V planes at the same time. This will have speed
advantages when using SSE2 (or higher) optimizations, since we can do both
the U and V rows together in a single xmm register.

This also renames filter16 to filter16y and filter8 to filter8uv so that it's
more obvious what each function is used for.
