Saurabh Shah 399667e7c4 overlay: upgrade
p#1: Remove WAIT and CHANNEL enums and usage. Replace BypassPipe with
     GenericPipe. Client expected to set alignments and parameters.
     Add transform combination enums.
p#2: Allow APIs to be called in any order. Do transform calcs in commit.
     Move ext type setter and getter functions.
p#3: Add calculations for 180 transform.
p#4: Add secure session support in rotator
p#5: Implement all rotations in terms of H flip, V flip and 90 rotation.
