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.

4a384de5b8 Split h264dsp and h264pred in configure. 
Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions
but not the weight/loopfilter functions.
This should reduce the size of builds with one of these derivatives but without
H.264 decoding itself.
