Only activate a connection upon receiving it's public key if it's an
...
incoming connection. When it's outgoing, we need to receive an ack first.

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

remove=1 but also active=0.

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.

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 :).
