- Non-blocking connect()s.

- Socket handling revamped to use sockaddr_t.
- tinc can now tunnel over IPv6.
- Handle all addresses and subnets in network byte order.
  Only convert them when they need to be printed.
- IPv6 subnets bigger than /128 now work.
- Use %s and strerror(errno) instead of %m.
