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.
Type-A modes always have an argument[0], but soju doesn't care about
them since it doesn't keep track of mode lists (ban/invite/.. lists).

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.

VARCHAR(n) is pointless in SQLite and is the same as TEXT. Don't
bother with a migration since they're equivalent.
Also remove some unnecessary DEFAULT NULL statements.
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.
