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().

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.

Perform the DC prediction reversal immediately after decoding all of
...
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.
When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.

Make decode_init fail if the huffman tables are invalid and thus init_vlc fails.
...
Otherwise this will crash during decoding because the vlc tables are NULL.
