This commit should prevent soju from trying to authenticate the user
prior to having received AUTHENTICATE messages, when the client eagerly
requests capabilities with CAP REQ seeing available capabilities
beforehand with CAP LS.
Since NULL = NULL is always FALSE, this query needs to use IS instead.
This should fix the flood of DeliveryReceipts in the DB.

Previously http.Server.ListenAndServeTLS would return a not very helpful
error about a failed open. This adds a check similar to the one in the
ircs case that should make it clearer to operators what the error is.
This allows users to set a default realname used if the per-network
realname isn't set.
A new "user update" command is introduced and can be extended to edit
other user properties and other users in the future.
Typically done via:
/notice $<bouncer> <message>
Or, for a connection not bound to a specific network:
/notice $* <message>
The message is broadcast as BouncerServ, because that's the only
user that can be trusted to belong to the bouncer by users. Any
other prefix would conflict with the upstream network.
The first MOTD upon connection is ignored, but subsequent MOTD messages
(requested by the "MOTD" message from the client, typically using a
/motd command) are forwarded.
