  Modified files:
    sys/netinet          tcp_syncache.c 
  Log:
  o Move setting/resetting logic of syncache timer from macro
    SYNCACHE_TIMEOUT to new function syncache_timeout().
  o Fix inverted timeout callout engagement logic to actually
    enable the timer for the bucket row.  Before SYN|ACK was
    not retransmitted.
  o Simplify SYN|ACK retransmit timeout backoff calculation.
  o Improve logging of retransmit and timeout events.
  o Reset timeout when duplicate SYN arrives.
  o Add comments.
  o Rearrange SYN cookie statistics counting.
