Move opername and privset storage to struct User, so it can exist for
remote opers.
On /oper and when bursting opers, send:
:foo OPER opername privset
which sets foo's opername and privset. The contents of the privset on
remote servers come from the remote server's config, so the potential
for confusion exists if these do not match.
If an oper's privset does not exist on a server that sees it, it will
complain, but create a placeholder privset. If the privset is created by
a rehash, this will be reflected properly.
/privs is udpated to take an optional argument, the server to query, and
is now local by default:
/privs [[nick_or_server] nick]
As it stands, oper hiding is rather messy and inconsistent. Add
SeesOper(target, source), which is true iff target should appear as an
oper to source. If I haven't missed something, all commands that reveal
oper status now use the same logic.
general::hide_opers_in_whois is a special case, and affects /whois only.
general::hide_opers is introduced, and has the same effect as giving
everyone oper:hidden. All commands that reveal oper status respect both.
Reloading modules sends CAP DEL followed by an immediate CAP NEW:
:staberinde.local CAP * DEL :account-tag
:staberinde.local CAP * NEW :account-tag
This isn't very nice. /modrestart is particularly bad. In order to avoid
doing this, we remember the capability set at the beginning of module
operations, compare that with the set afterwards, and report only the
differences with CAP {DEL,NEW}.
When a server disconnects the client_exit hook will only be called once
but there could be multiple servers and clients behind that server.
After any client exits, check if the agent is still present.
This only supports two addresses as the intended use is 1 IPv4 and 1 IPv6
address on a single-homed host, and the only supported configuration of
outgoing connections to other servers is to bind a single IPv4 or IPv6
address.
Outgoing servers are not added to the client hash until they reach
IsServer() status, so if they're unknown when they exit then don't
attempt to delete them.
Set current_capmask and then use it, instead of referencing target_p->localClient->caps again.
This makes the purpose of current_capmask a bit clearer.
