liboverlay: Refactor, bug-fixes, upgrade.

* Fix memory leak during copying pipe objects.
* Remove unused / unnecessary code.
* setMemoryId API is merged with queueBuffer.
* setParameter API is setTransform now.
* Rotator upgraded to:
  --Allow different rotator hardware types.
  --Remove dependency on MDP code.
  --Allocate memory only during first playback,
  close when the associated pipe is closed.
* Have single commit implementation.
* Include new format types.
* Remove WAIT and CHANNEL enums and usage. Replace BypassPipe with
  GenericPipe. Client expected to set alignments and parameters.
  Add transform combination enums.
* Allow APIs to be called in any order. Do transform calcs in commit.
  Move ext type setter and getter functions.
* Add calculations for 180 transform.
* Add secure session support in rotator
* Implement all rotations in terms of H flip, V flip and 90 rotation.
