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.

4538729afe Move sine windows to a separate file 
These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.
