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.

b790db1423 Keep batch tag for downstreams with batch cap
On upstreams without message-tags support, we do not advertise
message-tags anymore. Still, we want to send the batch tag when the
client explicitly requested it.

This fixes a critical issue where we drop the batch tag on chathistory
messages for upstreams that do not support message-tags.

b67b9b3cd2 Enable message-tags only when all upstreams support it
Previously, we would always advertise mesasge-tags. This made
downstreams believe they could send TAGMSG to the upstream, even though
the upstream did not support it.

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.

d8ca6d2222 Enable resetting a BOUNCER NETWORK port
When a client sends BOUNCER CHANGENETWORK with no value (or an empty
port value), this means it wants to reset the port value to its default
value.

Previously we considered an empty port as an actual valid, empty port
value, which would then be used to connect to the server (dial
'example.com:' (ie 'example.com:0'), which failed.

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).

2ac9bd9c94 Require an explicit * network suffix for multi-upstream
Most users will connect to their server with `<username>` as their
username in order to configure their upstreams.

Multi-upstream can be unintuitive to them and should not be enabled on
that first connection that is usually used for upstream configuration.

Multi-upstream is instead a power-user feature that should be explicitly
enabled with a specific network suffix.

We reserve the network suffix `*` and use it a special case to mean that
it requests multi-upstream mode.

f5b16dc00c Send any welcome error messages to the downstream
Currently, if we fail connecting to a new networking during welcome, we
send no error message to the client, and the connection remains open in
an undefined state.

Given the input:

  NICK nick
  USER user/invalid.xyz s e r
  PASS pass

soju will fail to connect, add a message to its own logs, but will
return no message to the downstream.

This fixes the issue by forwarding the error message if it is an IRC
error message (which it is for connecting to new networks).

We should probably also close the connection after the message is
written, because it leaves the connection in an undefined state. This is
TODO for now because we'd have to wait for the error message to be
written out first, which is non-trivial.

9647711921 Fix build on systems without syscall.Rlimit
On some systems (namely Windows), syscall.Rlimit is not defined, and
makes the build fail.

This fixes the build by making the rlimit calls only run on archs where
it is defined, defaulting to a stub on other systems.
