Log message:

Based on discussion with Bleep, and the change in /wallops implementation
that has taken place on u2.10.10.pl14, sendcmdto_flag_butone() has been
recast to broadcast them to all servers, regardless of what sorts of users
those servers have on/behind them.  This reduces CPU wasted on /wallops to
the minimum practical, with only a small increase in protocol overhead--in
my opinion, that overhead is not enough to worry about.

+	* ircd/send.c (sendcmdto_flag_butone): recast to just broadcast to
+	all servers, rather than to only servers that have +w/+g/whatever
+	users on them; among other things, this removes that atrocity
+	known as sentalong[] from this function
+
 	* ircd/m_admin.c: must include ircd.h to declare "me"; must
 	include hash.h to declare FindUser()
