Well, that's good question. Actually, this structure consists from several
arrays defined in VP8. See https://bitbucket.org/paullo612/cedarx-vp8-test/src/
default/src/vp8.c function fill_probs_table(). It's my understanding that this
was reverse engineered from CedarX binary library. Instead of building array
every time codec is started, I just precomputed it. I agree that it needs some
explanation.

Ok.

Well, this table can even go in common header... I'm not sure how many future
codecs would need it. For now, it can stay here but maybe renaming it to
vp8_k_mv_entropy_update_probs would be enough (instead of comment)?
