5a28aa7b8b Add LocalDiscovery option which tries to detect peers on the local network.
Currently, this is implemented by sending IPv4 broadcast packets to the
LAN during path MTU discovery.

6d08eb1614 Fix sparse warnings and add an extra sprinkling of const.
This is more or less the equivalent of Sven-Haegar Koch's fixes in the 1.1
branch.

d15099e002 Be liberal in accepting KEY_CHANGED/REQ_KEY/ANS_KEY requests.
When we got a key request for or from a node we don't know, we disconnected the
node that forwarded us that request.  However, especially in TunnelServer mode,
disconnecting does not help. We now ignore such requests, but since there is no
way of telling the original sender that the request was dropped, we now retry
sending REQ_KEY requests when we don't get an ANS_KEY back.

5cbddc68ba Use uint32_t instead of long int for connection options.
Options should have a fixed width anyway, but this also fixes a possible MinGW
compiler bug where %lx tries to print a 64 bit value, even though a long int is
only 32 bits.

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.

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.
