* released 1.1.20
* fixed two problems with time-outs, one where a server would be logged as
  timed out during transfer that take longer to complete than the fixed
  time-out, and one where clients were logged as timed-out during the data
  phase because they didn't have anything to send. This sometimes caused
  slow client connections to close too early while in fact there was no
  problem. The proper fix would be to have a per-fd time-out with
  conditions depending on the state of the HTTP FSM.
