c73d99e672 Separate format conversion DSP functions from DSPContext.
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

d461a47317 Rearrange MpegEncContext to simplify access from asm
This moves the fields needed by asm near the top, before any
structs or other members which complicate the offset calculation.
Modifying other structs will no longer require updating the offsets,
and the asm code is slightly simpler due to the smaller offsets.

5b5083b5fe Don't declare a pcm_dvd encoder.
The PCM_DVD encoder would be left unused, as allcodecs.c properly declared
it as being decoder-only, but it would still be built into the object file.

Since there is no block of code to properly encode this PCM format, it's
not a full codec.
