b7b1509d06 truemotion: forbid invalid VLC bitsizes and token values.
SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid
values larger than this in get_vlc2() (max_bits). tokens[][] can be
used as an index in deltas[], which has a size of 64, so ensure the
values are smaller than that.

This prevents crashes on corrupt bitstreams.

a05c41acd1 mp3dec: perform I/S and M/S only when frame mode is joint stereo.
Looks like some LAME versions produce dual stereo mode MP3s with
flags for intensity and middle stereo set. In this mode those flags
should be ignored like the reference decoder and derived ones do.

A call to decode_packet() does not always decode a complete WMA packet.
