Split tracking.c into several files

File tracking.c became rather huge and annoying to
maintain and it really contains several independent
areas of motrack pipeline.

Now we've got:

* tracking.c: general-purpose functions which are used
  by blender, clip editor, RNA and so.

* tracking_detect.c: feature detection functions
  (blender-side, logic is still in libmv).

* tracking_plane_tracker.c: blender-side 2D tracking logic.

* tracking_plane_tracker.c: plane track tracker.

* tracking_solver.c: functions for camera solving.

* tracking_stabilize.c: 2D stabilization functions.

* tracking_util.c: utility functions for all those files
  and which shouldn't be public.
