it runs off the end of a buffer; eventually, this should be replaced
with FFmpeg's internal bit reader which is hopefully more robust

decoder works great, this decoder is not completely and seamlessly
integrated yet with FFmpeg

Adds --enable-theora/--enable-vorbis/--enable-ogg to configure
If compiled WITHOUT --enable-theora, native VP3 decoder is used

- removed old MB decoding functions, and moved around macros to be used in
the previously unused code, which match better msmpeg4.c/whole MPV
framework
- cleaned (not yet functionnal, lots missing) DC prediction
- trying to pass the proper coded status to block decoder

segfaults on all .cin videos from Quake II.

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.

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.

which isn't the advanced one; and indeed, using adv. profile parser fails.
Using normal parser works, and that's what is done
- attempt at taking care of stride for NORM2 bitplane decoding
- duplication of much code from msmpeg4.c; this code isn't yet used, but
goes down as far as the block layer (mainly Transform Type stuff, the
remains are wild editing without checking). Unusable yet, and lacks the AC
decoding (but a step further in bitstream parsing)
