9e7b62f0fb twinvq: set block align for codecs and use it in size checks 
This both allows factoring out size check for both MetaSound and TwinVQ-VQF
decoders and fixes the situation when there are several MetaSound frames
stuffed together (that happens in 8kHz @ 8kbps MetaSound in ASF for example).

bc909626b0 twinvq: move all bitstream reading into single place 
This is required for the future addition of VoxWare MetaSound decoder, for its
functions are mostly the same but bitstream reader is completely different
and bitstream format is slightly different too.

4bf2e7c5f1 twinvq: fix out of bounds array access 
ModeTab.fmode has only 3 elements, so indexing it with ftype
in the initialier for 'size' is invalid when ftype == FT_PPC.

This fixes crashes with gcc 4.8.

7b966566da vqf/twinvq: pass vqf COMM chunk info in extradata 
This is needed because the twinvq decoder cannot rely on bit_rate to be set.
The API documentation says that bit_rate is set by libavcodec, not by the
user.
