Fix adding feather points when there's deformed spline for mask

Deformed spline should be re-evaluated after adding new feather points
Used both BKE_mask_update_display and DAG_id_tag_update because of:

- If adding feather point is happening from macro which adds point and
slides it, deformed spline should be updated immediatelly so sliding
operator will use updated feather,
- If adding happens outside of such macro, update DAG is necessary to
make needed updates in other areas (such as compositor, i.e.)

minor cleanup

use malloc for point arrays since they are filled in immediately.

minor refactor - use float (*)[2] for 2D point arratys.

Fixed memory leak caused by not freeing uw array for points in deformed spline

patch from pete larabell - feather support for masking.

No need in +x flag for mask_shapekey.c
