under FreeBSD now :).

34f9e6cf2d - route.c is now used to determine destination

- made functions that don't return useful information void

a56df1e06b - Allow ASN1 style keys to be in the config files. 
Note: tinc ignores private key in the main config file, tinc.conf,
  because it should really be in a separate file.
- When generating new keys, check if name is known and by default append
  the public key to the host configuration file (otherwise rsa_key.pub).
