Changes to the asm are not merged, they are left for volunteers or
in their absence for later.
The changes this merge introduces are reordering of the function
arguments

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.

This prevents emulated_edge_mc from not undoing mvy*stride-related
integer overflows.

Currently all uses of the emu edge code as well as the code itself
assume int linesize
changing some but not changing all would introduce a security issue
once all use this typedef a simple search and replace can be
done to switch them all to ptrdiff_t

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().
