13eb6b9097 Make ff_h264_find_frame_end static to h264.c; delete h264_parser.h 
The header is empty after making the function static, so delete it and
drop its usage.

44002d8323 Don't do edge emulation unless the edge pixels will be used in MC. 
Do not emulate larger edges than we will actually use for this round of
MC. Decoding goes from avg+SE 29.972+/-0.023sec to 29.856+/-0.023, i.e.
0.12sec or ~0.4% faster.

6ed3b504f9 Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables. 
This symbol is only ever used to calculate the non-hardcoded tables, so
only enable it in that case, and static to the source unit that uses it.

5b5083b5fe Don't declare a pcm_dvd encoder. 
The PCM_DVD encoder would be left unused, as allcodecs.c properly declared
it as being decoder-only, but it would still be built into the object file.

Since there is no block of code to properly encode this PCM format, it's
not a full codec.

938f72e199 Remove "libmpeg2" bitstream reader 
Using the libmpeg2 reader causes errors in a multitude of places,
including MPEG and H264 codecs.  As the advantage of this reader
is questionable, removing it seems the sensible course of action,
especially considering the simplifications this allows elsewhere
with the bit cache size increasing from 17 to 25 bits as minimum.

f14bdd8e75 H.264: Partially inline CABAC residual decoding 
Improves CABAC performance about ~1.2%.

Trick originates from x264 and has also been used in ffvp8.  It's useful because
coded block flags are usually zero, so it helps to have the early termination
inlined into the main function.

7cc4be58b4 Rearrange exponent buffer to group all blocks for a single channel together. 
This will allow for faster and simpler processing of all blocks at once.

2a1f431d38 H.264/SVQ3: make chroma DC work the same way as luma DC 
No speed improvement, but necessary for some future stuff.
Also opens up the possibility of asm chroma dc idct/dequant.

290fabc684 Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. 
Doesn't help speed as there isn't an asm implementation yet, but consistency
is a good thing.

Useful so that we don't have to run the hierarchical DC iDCT if there aren't
any coefficients.  Opens up some future opportunities for optimization as well.
