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.

Changed ping behaviour (backwards compatible). If we don't have any data
...
to send, we don't need to check if the connection is still alive.
Furthermore, if we receive any kind of data from the other end, we know
it's alive, so we don't need to check it either. So, PING requests are
only sent if we send packets but there is no response.

Added new config variable "ProxyMode". If enabled, all outgoing packets
...
are sent to the uplink (ConnectTo), which will have to forward them for
us (kernel should do that). This is for people behind firewalls.

Previous fix fixed. Meta protocol should be really flawless from now on!

Meta protocol overhaul. Tinc is now incompatible with previous versions,
...
furthermore this version does NOT work yet because of a problem with
sending keys (these should be converted to base36 or something like that).
It is possible to telnet to the tinc daemon now and type some commands
by hand though :).

When trying to talk to a host that is in the netmask of a tinc server but
...
not the tinc server itself, and no keys have been exchanged yet, the key
request would be directed to the host instead of the server. Fixed.
