mpegaudiodec: Skip only bad frames instead of the whole packet.
...
On frame decoding failure, return an error if the frame is the same size as
the whole packet, otherwise just log an error message and return the number
of bytes consumed.

g722dec: remove the use of lowres for half-rate decoding.
...
It is broken because an AVCodecContext can be opened/closed multiple
times, and sample_rate is getting divided by 2 each time that happens.
This removes the only use of lowres for audio.
