Unroll main loop so the edge==0 case is seperate.

This allows many things to be simplified away.
h264 decoder is overall 1% faster with a mbaff sample and
0.1% slower with the cathedral sample, probably because the slow loop
filter code must be loaded into the code cache for each first MB of each
row but isnt used for the following MBs.

Gcc idiocy fixes related to filter_mb_edge*.
...
Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

H264 DXVA2 implementation
...
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h )
The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

Change code so it uses 2 adds instead of one FFABS.
...
About 1% faster ff_ac3_bit_alloc_calc_psd on Intel Atom, overall speedup
not measurable though.
Should have a bigger effect on systems without cmov or with very slow cmov.

Implement alpha channel decoding for BGR HuffYUV.
...
Since BGR24 is decoded as BGR32, fill its alpha channel with 255
using the appropriate predictors.

AAC: Unswitch loop over window groups in decode_spectrum_and_dequant()

GCC should be able to do this, but doesn't. Slightly faster code.

AAC: simplify some calculations in decode_spectrum_and_dequant()
...
Simplify cur_band_type, group_len, and coef/offset calculations. This
makes the code easier to read and slightly faster.

AAC: Compress codebook tables and optimise sign bit handling
...
The codebooks each consist of small number of values repeated in
groups of 2 or 4. Storing the codebooks as a packed list of 2- or
4-bit indexes into a table reduces their size substantially (from 7.5k
to 1.5k), resulting in less cache pressure.
For the band types with sign bits in the bitstream, storing the number
and position of non-zero codebook values using a few bits avoids
multiple get_bits() calls and floating-point comparisons which gcc
handles miserably.
Some float/int type punning also avoids gcc brain damage.
Overall speedup 20-35% on Cortex-A8, 20% on Core i7.

SIPR: kill variable-length arrays
...
Two of these are in fact constant size, so use the constant instead of
a variable in the declarations. The remaining one is small enough
that always using the maximum size is acceptable.

Split cavlc out of h264.c.
...
Seems to speed the code up a little...
The placement of many generic functions between h264.c and h264.h is still open
Currently they are a little randomly placed between them.

Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just

called once per MB in worst case and doesnt seem to benefit from static inline.
Actually the code might be a hair faster now (0.1% according to my benchmark but
this could be random noise)
