session/tcp: improve preallocated segment handling
- add preallocated segment flag - don't remove pre-allocated segments except if application detaches - when preallocating fifos in multiple segments, completely fill a segment before moving to the next - detach server application from segment-managers when deleting app - batch syn/syn-ack/fin (re)transmissions - loosen up close-wait and time-wait times Change-Id: I412f53ce601cc83b3acc26aeffd7fa2d52d73b03 Signed-off-by: Florin Coras <fcoras@cisco.com>
