Experimental operator to cleanup mask shapekeys

For every shapekey operator check whether mask shape
stays within given tolerance and if so, shapekey is
removing.

TODO:
- Radius and weight are not handled completely crorrect,
need some smarter way to handle them.
- There're huge issues with depsgraph tag update for
mask and acutal mask update -- worked around by manual
call of BKE_mask_evaluate from places where shapekeys
are removing.

Would need to look further into this in trunk.

Masks tracking operators

Added an operators which tracks the whole masks
in clip editor. Namely, this operators are tracking
selected splines of active spline layer.

This uses the same exact region tracker as motion
tracker used for ages, just marker is created from
mask spline. Pattern area will match the size of
spline's bounding box (without feather taken into
account!). Search area is currently hardcoded to
1.5x times bigger than marker's pattern area.

Settings for the tracked are used from default
tracker settings (which are in T-panel). So for
this added special panel to mask mode which
contains default tracker settings.

Matching will be ignored and Previous Frame
matching will be used.

Speed is also currently hardcoded to realtime.

This new tracker operators are using the same
shortcuts as regular tracker.

TODO:
- Feather support.
- Better deal with search area size.
- Think of tracking speed control.

This is an experimental feature, might crash or
do not behave as you expect it to behave.

Update libmv to version from own branch

Brings in the changes:

- Optimized keyframe selection, which is reached by
switching pseudoInverse from SVD to eigensolver.
- Cleans up comments and functions names.

Also cleaned code in libmv-capi a bit.
