- Instead of logging an error when remote end closes the connection,
...
we print a nice message if appropiate debug level is set.
- If we get ADD_HOSTs or DEL_HOSTs for ourself, then connection lists
are really messed up. We restart, and hope our problems go away.

improve connection list consistency, ensures the tree property, and

- Removed all IP_ADDR_S macros, because gettext doesn't like them. Each

connection now has two hostnames: real_hostname (replacing the old),
and vpn_hostname. In those places where hostnames really aren't usefull
IP_ADDR_S has been replaced by %d.%d.%d.%d.

wrong (first two arguments swapped). Should probably be doublechecked.
- Don't retry to connect to hosts with different protocol versions.

7f7e158aae
Large cleanup:
...
- Removed hostname lookup (it blocks, and you can always do it yourself)
- Reorganized debug levels (after hints from Axel M�ller):
0 Startup message and errors
1 Connection logging
2 Meta protocol information
3 Verbose meta protocol (includes copy of transmitted requests)
4 Packet information (logs transmission/errors of UDP packets)
5 Verbose packet information (every single byte, not implemented yet
to protect ourselves from filling up /var/log directories)
- Made log messages more consistent

First step for implementation of the "indirectdata" directive. This should

allow _leaf_ tincds to be behind firewalls.
The protocol has changed and is INCOMPATIBLE with previous versions. The
PROT_CURRENT value has been incremented.

Only accept an ADD_HOST request for a host that already exists in our conn_list if the nexthop field matches the sender. This is a workaround for older clients.
