9d8bb0318a Small refactoring: Instead of 4 loops for decoding AC coefficients based
on their grouping, create one loop that indexes into a table of AC VLC
tables.

There is also a small optimization here: Do not call unpack_vlcs()
if there are no fragments in the list with outstanding coefficients.
My profiling indicates that this can save upwards of 1 million
dezicycles per frame throughout the course of unpack_dct_coeffs().

098523eb28 Use a list to track which fragments coded in this frame still have
outstanding coefficients yet to be decoded from the bitstream. Once a
fragment reaches end-of-block, remove it from this new list. This change
makes the VP3/Theora entropy decode process dramatically faster due to
not having to iterate incessantly over fragments which have already been
fully decoded.

76c4a644ee Fix an issue uncovered by commit 20623:
The init functions of mpc7 and mpc8 check whether the vlc has been
initialized already and return early if this is the case (eg by calling
init a second time).
But avctx->sample_fmt and channel_layout is set after the vlc initialization,
causing it not to be set on the second call of init.

Move all manipulations of avctx before the initialization of the vlc,
so that it is always set.
