2ba13fdefc upstream: use context to set connectToUpstream timeout
This allows the timeout to apply to the whole sequence of
operations, as opposed to just Dial.

abe5291b62 Add support for the upstream echo-message capability
This adds support for upstream echo-message. This capability is
enabled when the upstream supports labeled-response.

When it is enabled, we don't echo downstream messages in the downstream
handler, but rather wait for the upstream to echo it, to produce it to
downstreams.

When it is disabled, we keep the same behaviour as before: produce the
message to all downstreams as soon as it is received from the
downstream.

In other words, the main functional difference is that when the upstream
supports labeled-response, the client will now receive an echo for its
messages when the server acknowledges them, rather than when soju acks
them.

Additionally, uc.produce was refactored to take an ID rather than a
downstream.

846c99dedc Queue WHOIS commands
This avoids having more than one in flight at a time (avoids
hitting rate limits a bit) and routes back replies to the correct
downstream connection (even if labeled-response isn't supported).

cae248f672 Add support for the wip soju.im/read capability and READ command
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.
