88bd7fdc82 Drop DCTELEM typedef
It does not help as an abstraction and adds dsputil dependencies.

8c53d39e7f lavc: introduce VideoDSPContext
Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

45635885e4 mpegvideo: increase edge_emu_buffer size for VC1
The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma
and needs more space. That was not a problem before f1d8763a02
since the size for edge_emu_buffer was always calculated with 2 byte per
pixel since the linesize was not known.

Fixes occasionally fate errors in vc1_sa10143.

f1d8763a02 mpegvideo: allocate scratch buffers after linesize is known
Since we can't know which stride a custom get_buffer() implementation is
going to use we have to allocate this scratch buffers after the linesize
is known. It was pretty safe for 8 bit per pixel pixel formats since we
always allocated memory for up to 16 bits per pixel. It broke hoever
with cmdutis.c's alloc_buffer() and high pixel bit depth since it
allocated larger edges than mpegvideo expected.

Fixes fuzzed sample nasa-8s2.ts_s244342.

This does not seem to have an effect currently. Fate-h264 passes with
THREADS=1..16 and both threading types as before. It fixes however a
segfault during error resilience with my adaptive-frame-mt patchset.
A picture in use during error resilience gets realloced in another
thread in the fuzzed sample sample_varPAR.avi_s226019.
