* searchbyserver() split out into two functions, correcting the bug which

  would cause a server with a wildcard C:Line to continue to attempt to
  connect to its uplink even after a connection was established.
* When connecting to another server, it was possible that the IRCd would
  send its PASS/SERVER command pair again in error.  This would generate
  warning messages on the receiving server side stating "Refusing to comply
  with supposedly bogus SERVER command."
* When a channel was both +k and +l, the IRCd would incorrectly interpret
  the incoming SJOIN message for that channel.  (i.e. +kl 1 1 would return
  +k 11)
* The IRCd now crunches modes on an incoming SJOIN message.
