session: add support for memfd segments
- update segment manager and session api to work with both flavors of ssvm segments - added generic ssvm slave/master init and del functions - cleanup/refactor tcp_echo - fixed uses of svm fifo pool as vector Change-Id: Ieee8b163faa407da6e77e657a2322de213a9d2a0 Signed-off-by: Florin Coras <fcoras@cisco.com>
