bf2bc926f0 - a lot less overflows when decoding frames 
- no more error with norm6 codes
- almost skipped frames (~110 bits) are not overflowed
However:
- there are very few bits left in those frames, so I wonder if enough MB
data is actually left
- NORM6/DIFF6 (4/5) bitplanes are a lot more present, which I don't find
obvious.

5e424311dd - add another way to decode norm6 VLC; modify VLC_NORM6_METH0D define in 
vc9data.h to select the behaviour
- modified decode_b_picture_primary_header so that
decode_bi_picture_header is no more required

Fixes:
- modifications for some more using of MpegEncContext
- fixed a bit frame type decoding
- switch from pointers to index for AC tables
- corrected P CBPCY decoding (p_cbpcy += 4)

0d33db8a4d In that patch: 
- avctx and gb elements were removed from VC9Context, hence a larger diff
- some code was added to h263dec.c regarding CODEC_ID_WMV3 (should apply to CODEC_ID_VC9 too)
- VLC tables and other related tables were made global whenever this seemed necessary; appropriate changes were therefore made to other parts of the code using those tables
- the change for the bitplane management to a struct (some of them should eventually be mapped to MpegEncContext arrays) wasn't associated with the proper frees; should be fixed now

e5540b3fd3 Fixes: 
- i/p/b_decode_mbs functions now checks the proper values (from
bitplane). I didn't find it very clear, but it seems "raw" = "to read at
the MB layer". I used a structure, but we could spare that indirection and
add a flag in the VC9Context for each array.
- Properly decode (or so I think) the CBPCY (as it is predicted)
- many more things
