session: segment manager refactor
- use valloc as a 'central' segment baseva manager - use per segment manager segment pools and use rwlocks to guard them - add session test that exercises segment creation - embed segment manager properties into application since they're shared - fix rw locks Change-Id: I761164c147275d9e8a926f1eda395e090d231f9a Signed-off-by: Florin Coras <fcoras@cisco.com>
