Session layer improvements
Among others: - Moved app event queue to shared memory segment - Use private memory segment for builtin apps - Remove pid from svm fifo - Protect session fifo (de)allocation - Use fifo event for session disconnects - Have session queue node poll in all wk threads Change-Id: I89dbf7fdfebef12f5ef2b34ba3ef3c2c07f49ff2 Signed-off-by: Florin Coras <fcoras@cisco.com>
