Acts1631 68131a09be ctcp: cap CTCP body length used in dynamic signal name (IRC path) 
The body of a CTCP message received over IRC (PRIVMSG/NOTICE) is
concatenated into a dynamic signal name and emitted via signal_emit
in ctcp_msg/ctcp_reply (ctcp.c) and the DCC sub-dispatch
ctcp_msg_dcc/ctcp_reply_dcc (dcc.c). The first whitespace-separated
token becomes the CTCP command and is interned as a signal name; the
remainder is delivered to any matching handler, including loaded
perl scripts.

signal_emit interns unknown signal names permanently in the global
signal-name registry (module_get_uniq_id_str g_strdup's the name into
two hash tables that are freed only at exit). With no length or count
cap on the IRC-CTCP path, a remote user sending many distinct CTCP
command names grows the registry without bound, exhausting memory and
crashing the victim's irssi.
