- renaming the AC coding set variable names to more meaningful ones
...
- 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

- samples from mplayer ftp in the "adv" profile seem to have profile=2,
...
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)

- 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.
