d5b56bbba5 Disable PMTUDiscovery in switch and hub modes. 
In switch and hub modes, tinc does not generate ICMP packets in response to
packets that are larger than the path MTU.  However, if PMTUDiscovery is
enabled, the IP_MTU_DISCOVER and IPV6_MTU_DISCOVER option is set on the UDP
sockets, which causes all UDP packets to be sent with the DF bit set, causing
large packets to be dropped, even if they would otherwise be routed fine.

503c32eb0e Use a global list to track outgoing connections. 
Previously an outgoing_t was maintained for each outgoing connection,
but the pointer to it was either stored in a connection_t or in an event_t.
This made it very hard to keep track of and to clean up.

Now a list is created when tinc starts and reads all the ConnectTo variables,
and which is recreated when tinc receives a HUP signal.

26b490e86b Make sure IPv6 sockets are IPv6 only. 
This will get rid of the "Can't bind to 0.0.0.0 port 655/tcp: Address already
in use" message on Linux.

228e7a5c8f Apply patch from Scott Lamb adding an output buffer for the TCP sockets. 
This helps coalescing multiple send_meta() commands into one TCP packet.
Also limit the size of the output buffer before dropping PACKETs.
