Add support for detached channels 
Channels can now be detached by leaving them with the reason "detach",
and re-attached by joining them again. Upon detaching the channel is
no longer forwarded to downstream connections. Upon re-attaching the
history buffer is sent.

Remove network.upstream 
This is an artifact from when we used locks. No need for this anymore.

Add upstreamConn.caps 
Instead of adding one field per capability, let's just have a map, just
like downstreamConn.

Add support for away-notify 
This makes use of cap-notify to dynamically advertise support for
away-notify. away-notify is advertised to downstream connections if all
upstreams support it.

19854b7ec7 Unmarshal nicks in texts of PRIVMSG and NOTICE from downstreams 
When writing a PRIVMSG or NOTICE on a channel, it is very common to use
autocompletion to mention other users on that channel. When using soju
in multi-network mode, all users will have their nicked suffixed by
`/network`. This suffix should be removed before sending it upstream.

This adds support for removing all `/network` suffixes in messages sent
to a channel of that network.

Per-entity ring buffers 
Instead of having one ring buffer per network, each network has one ring
buffer per entity (channel or nick). This allows history to be more
fair: if there's a lot of activity in a channel, it won't prune activity
in other channels.

We now track history sequence numbers per client and per network in
networkHistory. The overall list of offline clients is still tracked in
network.offlineClients.

When all clients have received history, the ring buffer can be released.

In the future, we should get rid of too-old offline clients to avoid
having to maintain history for them forever. We should also add a
per-user limit on the number of ring buffers.
