Libmv: Replace region tracker with autotracker in Blender

The title actually tells it all, this commit switches Blender to use the new
autotrack API from Libmv.

From the user point of view it means that prediction model is now used when
tracking which gives really nice results.

All the other changes are not really visible for users, those are just frame
accessors, caches and so for the new API.
