This adds only yuv420p10, others are trivial to add after this commit
and will be added in a subsequent commit.
Currently the implementation is not optimized, optimizations will be
added later

Sample timings on ped1080p.webm (of the ssse3 functions):
iadst_idct:  4672 -> 1175 cycles
idct_iadst:  4736 -> 1263 cycles
iadst_iadst: 4924 -> 1438 cycles
Total decoding time changed from 6.565s to 6.413s.

Also fix trac ticket #3296.

In particular:
* set default value for accuracy to 15 (max)
* add zoomspeed for dynamic zoom (optzoom=2)
* make camera path optimization algorithm configurable
* update optzoom documenation in code to use new localmotions calculation function commandline arguments
* add debug option in vidstabtransform

Players that conform to the specification can only playback such
files correctly on big-endian hardware.

Fixes ticket #3311.

This allows decoding broken mkv files containing G.726 audio.

The value is wrong and leads to broken files.
