Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context"

Browse Source 
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.
