ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

9885284c22 Check level_prefix a bit (this just checks the max our bitreader can handle, 
as i did nt find a limit in the spec)
This should stop cavlc_decode_residual() on a zero bitstream

69cc31832f Move check for and call of predict_field_decoding_flag() from the mb code to 
the row code. This function would only be needed on a MB basis for MBAFF+FMO

996b099a0f Branchless setting of MB_TYPE_8x8DCT. 
Not benchmarked as i failed to find a sample that uses this one. But it should be faster.

1f445f5473 Move dquant check into qscale overflow check. 
This should be faster (couldnt meassue a difference), and its less picky
on slightly out of spec dquant.

c988f97566 Rearchitecturing the stiched up goose part 1 
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.

ddd60f28d8 Replace cabac checks in inline functions from h264.h with constants. 
No benchmark because its just replacing variables with litteral constants
(so no risk for slowdown outside gcc silliness) and i need sleep.

8e71d89a7b Move golomb_to_int*cbp tables back to h264_data.h as svq3.c used them. 
Yes i did compile&test, no svq3.c was not recompiled.

e1e949026e 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.

f6f7d15041 h264: don't touch H264Context->ref_count[] during MB decoding 
The variable is copied to subsequent threads at the same time, so this
may cause wrong ref_count[] values to be copied to subsequent threads.

This bug was found using TSAN.
