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.

mpeg12: fix mpeg_decode_slice context parameter type

Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context"
...
This reverts commit da22ba7df4
since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.
