overlay: pipe reservation mechanism for overlay
This change provides APIs for this mechanism. In a case where
pipeid corresponding to the layer needs to be reserved, then pipe
session could be initiated for that pipe. This will ensure that
the pipe is not garbage collected, and is manually destroyed when
the session (or pipe requirement) has been ended. This change
also provides the api to locally allocate the dest for the given
reserved overlay pipeid.
