* 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.
