Overall tcp performance improvements (VPP-846)
- limit minimum rto per connection
- cleanup sack scoreboard
- switched svm fifo out-of-order data handling from absolute offsets to
relative offsets.
- improve cwnd handling when using sacks
- add cc event debug stats
- improved uri tcp test client/server: bugfixes and added half-duplex mode
- expanded builtin client/server
- updated uri socket client/server code to work in half-duplex
- ensure session node unsets fifo event for empty fifo
- fix session detach
