reject: Remember and send reasons for rejections
rejectcache entries can now use either a K-line aconf or a static
string as a reason. This will be sent in a 465 numeric before the usual
ERROR. In the case of K-lines, it resembles the 465 you would have been
sent without being rejected:

; nc -s 127.6.6.6 127.0.0.1 5000

m_modules: make modreload work like restart
/modrestart used to be implemented as a normal command and could crash
when used remotely because it would reload m_encap, which was on the
call stack at the time. This was fixed in 41390bfe5f. However,
/modreload has exactly the same problem, so I'm giving it the
same treatment.

Incidentally: This bug was first discovered in ircd-seven, where the
`/mod*` commands themselves live in the core, so m_encap was the only way
the crash could happen (and it didn't most of the time, because m_encap
would only be moved if you got unlucky). But `/mod*` are in modules in
charybdis, so /modrestart would have unloaded the code it was in the
middle of executing. With that in mind, I'm not sure how it ever
appeared to work.

strip_unprintable: clarify type conversion

Propagate OPER
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]

Rework oper hiding
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.

Deferred capability notifications from modules
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}.

m_sasl: check if the agent is present after every client_exit
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.

Add basic SCTP listener support that binds to multiple addresses
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.

echo-message should work for privmsg/notice to another user
Build the same message but send it to the local client first,
so that the echo-message capability works. But don't do it when
sending a message to yourself.

listener: use exit_client instead of free_client
As well as leaking a connid and leaving the connection open,
these calls to free_client() leave the client in the unknown_list
causing check_unknowns_list() to crash when either ptr->data
(ptr being the freed client_p->localClient->tnode) is NULL or
when client_p->localClient is NULL.

Flag the client as an IO error so that we don't try to send it
any data (as this is not a normal plaintext connection).

087555a00f ircd: introduce 'no-export' links
Links that are 'no-export' are not distributed to the rest of the IRC network (including local peers).
This provides a core primitive for 'anycasting' services (but the actual issue of synchronizing data in
a services package is left to the authors of the services package).
