READ lets downstream clients share information between each other about
what messages have been read by other downstreams.
Each target/entity has an optional corresponding read receipt, which is
stored as a timestamp.
- When a downstream sends:
READ #chan timestamp=2020-01-01T01:23:45.000Z
the read receipt for that target is set to that date
- soju sends READ to downstreams:
- on JOIN, if the client uses the soju.im/read capability
- when the read receipt timestamp is set by any downstream
The read receipt date is clamped by the previous receipt date and the
current time.
If the nickname we want is taken, fallback to another one by
appending underscores. Use MONITOR to figure out when we can request
our desired nick again.

If a client queues a high number of commands and then disconnects,
remove all of the pending commands. This avoids unnecessarily
sending commands whose results won't be used.
Once the downstream connection has logged in with their bouncer
credentials, allow them to issue more SASL auths which will be
redirected to the upstream network. This allows downstream clients
to provide UIs to login to transparently login to upstream networks.
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.

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 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.
Instead of ignoring detached channels wehn replaying backlog,
process them as usual and relay messages as BouncerServ NOTICEs
if necessary. Advance the delivery receipts as if the channel was
attached.
