Implement sack based tcp loss recovery (RFC 6675)
- refactor existing congestion control code (RFC 6582/5681). Handling of ack
feedback now consists of: ack parsing, cc event detection, event handling,
congestion control update
- extend sack scoreboard to support sack based retransmissions
- basic implementation of Eifel detection algorithm (RFC 3522) for
detecting spurious retransmissions
- actually initialize the per-thread frame freelist hash tables
- increase worker stack size to 2mb
- fix session queue node out-of-buffer handling
- ensure that the local buffer cache vec_len matches reality
- avoid 2x spurious event requeues when short of buffers
- count out-of-buffer events
- make the builtin server thread-safe
- fix bihash template threading issue: need to paint -1 across uninitialized
working_copy_length vector elements (via rebase from master)
