458446acfa lavc: Edge emulation with dst/src linesize 
Allow supporting files for which the image stride is smaller than
the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9
file or a 16x16 VP8 file with -fflags +emu_edge.

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

7d84826400 cavs: deMpegEncContextize 
It does not use any of the mpegvideo infrastructure, just a few fields
from the context.

Fixes a segfault with the emu edge flag, since emu edge buffer is now
allocated as a part of the frame buffer allocation and cavs calls
ff_get_buffer() directly, it does not use mpegvideo buffer management.

Fixes a memleak of the last frame.

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().

The square is always passed as 1 whenever the function is called and
thus the if block never gets executed.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
