- added the ability to kill off individual connections from SWAT (from
the status page)
- split the claim_connection() code into its own file
- fixed the claim_connection() code to lock the file when manipulating
it
- always claim a null connection at startup
- fixed a bug in the pidfile code
(This used to be commit abd4a17e21d12be3d1747e94ceb1915abaf135e3)
