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.

fcbe29bc4c No C99 initialisers, gcc 2.95.3 doesn't like it. 
Also make sure getopt.h is included.

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.

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.

  is not useful anyway.

  one for connections whose identity we know, sorted on id ofcourse...

698191fd2f - Prepended config_ to all configuration option names, because it confused

  packets.

183a8edd22 - Fixing-things pass: every source file compiles into an object file now, 
but linking tincd does not work yet (must link with openssl libs and
  define some missing functions).
