f2408ec9d7 Give IDCT matrix transpose macro a more descriptive name 
This also avoids a macro name clash and related warning on ARM.

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.

cb7ecb7563 vp56: Use hpeldsp instead of dsputil for half-pel functions 
This makes vp5 and vp6 independent of dsputil.

015821229f vp3: Use full transpose for all IDCTs 
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

f859678f3f vp56: Remove clear_blocks call, and clear alpha plane U/V DC only 
The non-alpha and alpha-Y planes are cleared in the idct_put/add()
calls. For the alpha U/V planes, we only care about the DC for entropy
context prediction purposes, the rest of the data is unused.

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().

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context 
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

5e1ba34bbb VP56: move vp56_edge_filter to new VP56DSPContext 
Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers.  The new
function pointers enable optimised implementations of the filters.

4% faster VP6 decoding on Cortex-A8.
