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.
A previous fix (d4b7bb02da) only fixed sending echo-message for
TAGMSG to self. We also need to send echo-message for TAGMSG to
other targets.

Instead of always requiring users to explicitly specify the network
name, guess it from the downstream connection.
Network commands are left as-is because it's not yet clear how to
handle them.
Right now there is no consistent ordering in the network list:
no ORDER BY in the DB, and network updates move entries to the end.
Let's always sort by network ID so that users don't see the entries
move around.
I've contemplated sorting by Network.GetName() instead, but:
- Clients have now way to figure out dynamic order changes, e.g.
when renaming a network.
- Some clients might use ISUPPORT NETWORK when a user hasn't
explicitly named a network, but soju won't use that for ordering,
leading to non-alphabetic ordering in the client.
Let's leave it to clients to sort the networks by display name if
they want to.
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.
The first reconnection attempt waits for 1min, the second the 2min,
and so on up to 10min. There's a 1min jitter so that multiple failed
connections don't try to reconnect at the exact same time.
