strip_unprintable: clarify type conversion
This type conversion is more easily shown to work as intended than the
conversion introduced in 9dcb9e169.

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.

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.

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).

authd: wait until the ssl connection is "open" before reading
It's useful to allow authd to run in parallel with ssl negotiation,
but if the ssld connection has plaintext data ready for reading
there's a race condition between authd calling read_packet() and
ssl_process_certfp() storing the certificate fingerprint. This
scenario would be bad for a server connecting because fingerprint
verification will fail.

Allow either operation to complete first, but wait until
ssl_process_open_fd() calls the ssl open callback before calling
read_packet().

ircd: server connection configuration
Fix the server connection configuration so that it can simultaneously
handle a hostname/IPv4/IPv6 for connecting and a hostname/IPv4/IPv6
for binding. Maintains backwards compatibility for matching a hostname
with a mask.

Multiple host/vhost entries can be specified and the last value for
each address family is stored. Hostnames that resolve automatically
overwrite the IP address.

Server connections can now be made to either IPv4 or IPv6 at random
as well as preferring a specific address family.

Implement the netsplit batch type.
This also lays the groundwork for the netjoin batch type, but that isn't
implemented yet. I don't like how some of this is implemented but it'll
have to do for now...

Change the way authd configures opm
It's a bit of a hack, but better than before. Rather than rehashing
(which could get us into an endless loop), we now segregate the
configuration phase (creating entries ircd-side in case we restart authd
later) and sending phases (when configure_authd() is called). Since we
have to call configure_authd() no matter what (to send timeouts etc.)
and we have to send this data to configure authd anyway, and sending
duplicate data is bad, this is the only way I can think of for now.
