mpeg4: support frame parameter changes with frame-mt
...
Adds a flag context_reinit to MpegEncContext to relieable keep track
of frame parameter changes which require a context reinitialization.
This is required for broken inputs which change the frame size but
error out before the context can be reinitialized.

mpegvideo: add reinit function for frame parameter changes
...
This is mainly required for frame parameter changes during frame based
multithreading but single threaded usage profits too from avoiding
ff_MPV_common_end()/ff_MPV_common_init() cycles.

mpegvideo: convert mpegvideo_common.h to a .c file
...
This file defines a single, huge function, MPV_motion(), which
although being declared inline is not actually inlined by the
compiler (for good reason). There is thus no sense in defining
this function in a header file, resulting in multiple copies of
it in the final library.

Interlaced images can have 32 references (16 per field), so limiting the

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.
