- Removed segfault bug in conf.c (must have been there for ages!)
- Made main_loop() signal proof
- #defined MAXTIMEOUT (15 minutes)
- If something really really bad happens, close all connections, wait
for MAXTIMEOUT seconds, and then restart tinc

- New semantics for BASIC_INFO, ADD_HOST and DEL_HOST requests. This will
improve connection list consistency, ensures the tree property, and
allows for recovery from situations where track of connections is lost.

- 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IP_ADDR_S has been replaced by %d.%d.%d.%d.

- Fixed KEY_CHANGED notification. A lot of notify_others() calls were
wrong (first two arguments swapped). Should probably be doublechecked.
- Don't retry to connect to hosts with different protocol versions.

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.

Terminate a connection on any error. Furthermore, disallow del_host,
add_host and other important requests until remote host has properly
authenticated itself.

Made tinc persistent. If no outgoing connection can be established right
after the start of the daemon, it won't quit anymore but will retry in 5
minutes. Also, 5 minutes is now the maximum time to wait for a retry.

Fix for a DoS attack:
A remote user could telnet to the tinc daemon and type only this line:
61 6 00000000/00000000:28f
This would deny any packets to be sent to other tinc networks (except
for to the hosts that run tincd's themselves). Solution is to skip
hosts in lookup_conn() that have not been activated yet.
Fixed potential conn_list table corruption:
If a new connection is accepted but a connection with the same subnet
would already exist in the connection list, the OLD connection is
terminated.

Documentation updates. Removed all references to configuration variable
"AllowConnect", since it is NOT used in tinc. Added information about
"VpnMask". Elaborated a bit about "private" and "virtual" networks.

Fixed last typo. Init.d now uses ifconfig command to set both the tap's IP
address as well as the correct route. Furthermore, if no VpnMask is given,
a default of 255.255.0.0 is chosen and a warning issued.

- Append your name to items if you're working on them.
- Remove them if you fixed the problem/implemented that feature.
- Add any (suspected) bugs.
