The MOTD indicates the end of the registration's message burst, and
the server can send arbitrary messages before it.
Update the supported capabilities, the nick and the realname before
MOTD to make it so client logic that runs on MOTD can work with
up-to-date info.
This function wraps a parent context, and returns a new context
cancelled when the connection is closed. This will make it so
operations started from downstreamConn.handleMessage will be
cancelled when the connection is closed.
As a bonus, the timeout now applies to the whole TLS dial
operation. Before the timeout only applied to the net dial
operation, making it possible for a bad server to stall the request
by making the TLS handshake extremely slow.
When on an unbound bouncer network downstream, we should return no
targets (there are none, because there are no upstreams at all).
When on a multi-upstream downstream, we should return no targets as we
don't support multi-upstream CHATHISTORY TARGETS.
Before this patch, we returned a misleading error message:
:example.com 403 :Missing network suffix in name
If a downstream of prefix host `foo` sends a message, the other
downstream of prefix host `bar` should receive an echo PRIVMSG with
prefix host bar.
This fixes a regression where no prefix host was sent at all.
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.
