9b394bc887 Ensure tinc compiles with gcc -std=c99. 
We use a lot of C99 features already, but also some extensions which are not in
the standard.

3308d13e7e Handle UDP packets from different and ports than advertised. 
Previously, tinc used a fixed address and port for each node for UDP packet
exchange.  The port was the one advertised by that node as its listening port.
However, due to NAT the port might be different.  Now, tinc sends a different
session key to each node. This way, the sending node can be determined from
incoming packets by checking the MAC against all session keys. If a match is
found, the address and port for that node are updated.

67df7fb7e1 Only send packets via UDP if UDP communication is possible. 
When no session key is known for a node, or when it is doing PMTU discovery but
no MTU probes have returned yet, packets are sent via TCP. Some logic is added
to make sure intermediate nodes continue forwarding via TCP.  The per-node
packet queue is now no longer necessary and has been removed.

116ba3b3da Cleanup: 
- Remove checks for specific OS's, instead check for #defines/#includes.
 - Use uint??_t where appropriate.
 - Mask handling functions use void pointers to get rid of silly casts.

c2b9c06062 - 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.

d9a62c6354 Added support for packet compression, thanks to Mark Glines. 
Add "Compression = <level>" to the host config files, where level can be
0 (off), or any integer between 1 (fast) and 9 (best).

82e3837109 Big bad commit: 
- Transition to new node/vertex/connection structures
- Use new configuration handling everywhere
- Linux tun/tap device handling cleanup
- Start of IPv6 support in route.c

It compiles, but it won't link.
