debc2adb16 CABAC support for MBAFF I frames patch by (Loïc Le Loarer < lll+ffmpeg m4x org) 
This patch corrects the support for I slice in CABAC and MBAFF mode.
This decodes correctly 6 more frames of the conformance suite.

6ba71fc467 This is the second patch for MBAFF support, this adds the deblocking 
filter code for the I slice.

With this patch, 4 more frames are decoded correctly from the
conformance streams.

3bf3d666a7 The cvs version 1.103 of h264.c brokes 13 conformance streams, this 
patch corrects this and decodes the same streams as version 1.102.

4e4d983e8b Set keyframe flag only on IDR-frames (needed for reordering across I-frames). 
Read vui bitstream restrictions (allows B-frame delay in advance, rather than waiting till we're out of order.)
Mark duplicate frames due to delay as duplicates.

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.

579448a083 - correct several errors on the deblocking accross slice boundaries. 
- 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.

5175b9376f add multi slice support 
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.
