subject: [Ffmpeg-devel] h264, protection against corrupted data

this also fixes a possible security issue (the sps and pps ids where not checked,
then used as index into an array of sps/pps structs which was then filled with data from the bitstream)

ebd624b662 optimize sign decoding code in decode_residual()
x86 is 4% faster on P3
C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C)
... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all

6fbcaaa0ef INTRA PCM macroblocks support patch by (Loic )lll+ffmpeg m4x org)
This patch adds the support for INTRA PCM macroblocks in CAVLC and CABAC
mode, the deblocking needed a small modification and so did the
intra4x4_pred_mode prediction.

With this patch, the 5 streams of the conformance suite containing INTRA
PCM macroblocks now decode entirely, 4 are completely corrects, 1 is
incorrect since the first B slice because of deblocking in B slice not
yet implemented.

The code is not optimized for speed, it is not necessary IPCM
macroblocks are rare, but it could be optimized for code size, if
someone want to do this, feel free.

0bf796340a H.264 multiple slice support in CABAC patch by (Loic (lll+ffmpeg m4x org)
3 more streams of the conformance suite decode to the
end instead of failing on an assert (CABACI3_Sony_B.jsv,
CABAST3_Sony_E.jsv and CABASTBR3_Sony_B.jsv), they are still false since
the first B slice probably because of deblocking in B slices not yet
implemented.

- add support for deblocking_filter_idc==2 which means no deblocking accross slice.
- correct MMCO with multiple slices.

5 more streams from H264 conformance suite are now correctly decoded.

for main profile H.264 streams. I have tested this on all H264
conformance streams and comparing the result with the current CVS
version, there is 8 streams which decode correctly more frames and 2
streams which are now completely correct with my patch.

This patch also correct some typo in comments.
