Session layer refactoring
Major refactoring of the session layer api - Add attatch api for application binding to the the session layer - Simplify listen/connect calls - Update application CLI - Add transport endpoint to accept callback - Associate segment manager to application and allow for multiple binds/connects per app Additional: - svm fifo cleanup - add fifo free, format fns - add fifo offset enqueue unit test Change-Id: Id93a65047de61afc2bf3d58c9b544339c02065af Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
