Add support for MONITOR in single-upstream mode.
Each downstream has its own set of monitored targets. These sets
are merged together to compute the MONITOR commands to send to
upstream.
Each upstream has a set of monitored targets accepted by the server
alongside with their status (online/offline). This is used to
directly send replies to downstreams adding a target another
downstream has already added, and send MONITOR S[TATUS] replies.

This has the following upsides:
- We can now routes WHO replies to the correct client, without
broadcasting them to everybody.
- We are less likely to hit server rate limits when multiple downstreams
are issuing WHO commands at the same time.
The message stores don't need to access the internal network
struct, they just need network metadata such as ID and name.
This can ease moving message stores into a separate package in the
future.
Make Network.Nick optional, default to the user's username. This
will allow adding a global setting to set the nickname in the
future, just like we have for the real name.

This adds support for WHOX, without bothering about flags and mask2
because Solanum and Ergo [1] don't support it either.
The motivation is to allow clients to reliably query account names.
It's not possible to use WHOX tokens to route replies to the right
client, because RPL_ENDOFWHO doesn't contain it.

That's what some widely used IRC servers do for their own services
(e.g. NickServ and ChanServ). This adds an additional level of
trust to make sure BouncerServ isn't typo'ed or impersonated.
This is a mecanical change, which just lifts up the context.TODO()
calls from inside the DB implementations to the callers.
Future work involves properly wiring up the contexts when it makes
sense.

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.
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.
