face578d56 Rewrite emu_edge functions to have separate src/dst_stride arguments. 
This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.

c341f734e5 Convert multiplier for MV from int to ptrdiff_t. 
This prevents emulated_edge_mc from not undoing mvy*stride-related
integer overflows.

57ed8debb9 wmv2: Propagate the wmv2 idct permutation type to the dsputils context 
This fixes encoding where the idct setting originally was set to
FF_IDCT_AUTO and dsputil chose a default idct with a non-null
permutation - even if the permutation tables were updated,
dct_quantize in x86/mpegvideoenc_template.c also checked the
value of this type variable.

e6bc38fd49 wmv2: move IDCT to its own DSP context. 
This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.

Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

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().
