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)

- 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

better names for globalized tables by me

check norm6 vlc validity as there are some bit sequences which dont corespond to any codeword, the other vlc tables all seem to be huffman tables though

- 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
