4ba5dbc0e4 mpegvideo: use hpeldsp instead of dsputil for half-pel functions. 
This also converts vc1, since that is mpegvideo-based.

  mpegvideo: drop vismv code

Conflicts:
	libavcodec/mpegvideo.c

vismv code works fine, and thus only the unused fields are droped

ee3c3dd523 ff_alloc_picture: free tables in case of dimension mismatches 
Fixes memory corruption
In theory this should not be needed but its better to check at
one place than to hope 50 other places set the flags correctly

8d061989dd lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs 
Not all hwaccels implement all codecs, so using one single list for
multiple such codecs means some codecs will be represented in the list,
even though they don't actually handle that codec. Copying specific
lists in each codec fixes that.

how it was found.

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.
