3d1b1caa6b Remove duplicate definitions of fullpel MC functions
This removes duplicated definitions of 8x8 and 16x16 fullpel MC
functions with various names reducing dsputil.o by 8k on x86_64.

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.

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.

4a384de5b8 Split h264dsp and h264pred in configure.
Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions
but not the weight/loopfilter functions.
This should reduce the size of builds with one of these derivatives but without
H.264 decoding itself.
