- flags are removed, since they were not used at all. Use options instead.
- indirectdata works now, tcponly almost...
- made functions that don't return useful information void
- Added some extra search functions to rbl routines
- Fix subnet_lookup()
- Reorder some syslog messages to make more sense
- daemon() is back
- Don't let scripts execute in parallel (gives race conditions, and
anyway something MIGHT just be configured which is necessary for further
execution of tinc itself)
- Accidently merged check_child() with execute_script().
- Small fixes
