44f8f61396 Try to set DF bit on BSDs as well. 
Every operating system seems to have its own, slightly different way to disable
packet fragmentation. Emit a compiler warning when no suitable way is found.
On OpenBSD, it seems impossible to do it for IPv4.

a9a803d566 Allow port to be specified in Address statements. 
This allows one to connect to use more than one port number to connect to
another node. The syntax is now:

Address = <hostname> [<port>]

c3acae034c Use IP_DONTFRAGMENT instead of IP_MTU_DISCOVER on Windows. 
This ensures the DF bit on outgoing UDP packets gets set on Windows when path
MTU discovery is enabled, reducing fragmentation.

35af4051c3 Fix a possible crash when sending the HUP signal. 
When the HUP signal is sent while some outgoing connections have not been made
yet, or are being retried, a NULL pointer could be dereferenced resulting in
tinc crashing. We fix this by more careful handling of outgoing_ts, and by
deleting all connections that have not been fully activated yet at the HUP
signal is received.

41a05f59ba src/net_socket.c: Bind outgoing TCP sockets to `BindToAddress'. 
If a host has multiple addresses on an interface, the source address of the TCP
connection(s) was picked by the operating system while the UDP packets used a
bound socket, i. e. the source address was the address specified by the user.
This caused problems because the receiving code requires the TCP connection and
the UDP connection to originate from the same IP address.

This patch adds support for the `BindToInterface' and `BindToAddress' options
to the setup of outgoing TCP connections.

Tested with Debian Etch on x86 and Debian Lenny on x86_64.

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.

38c25d62c2 Convert to libevent. 
This is a quick initial conversion that doesn't yet show much advantage:
- We roll our own timeouts.
- We roll our own signal handling.
- We build up the meta connection fd events on each loop rather than
  on state changes.

6362b12df7 Rename "event_t" to "tevent_t", along with associated functions. 
This relieves some confusion and problems during the libevent transition.
In particular, "event_add" was defined by both.
