TODO/bugs In SILC Server
========================
+ o Server signoff notifys does not go to normal servers from routers.
+
o On normal server the channel count can go negative (like -3 channels).
o Change the sever to connect to another server from low ports (706)
returns only the channels the server knows about. The protocol spec
does not prohibit of sending the LIST to the router.
+ o Announcements are incomplete: channel topics are not announced,
+ user modes (UMODE) are not announced.
+
o Incomplete IPv6 support:
o silcd/serverid.c and its routines supports only IPv4.
