Makes it easy to print debugging messages which aren't targeted at
the user. See [1] for motivation.

It's extra code for something clients should ignore because it's
unreliable and useless.

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.

Clients aren't supposed to do this, but in case they do, let's
send them an error.

Instead of hand-rolling our own rate-limiter based on goroutines,
use golang.org/x/time/rate.

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.

It wasn't decremented on error. While at it, increment it when
connecting to the upstream network.

This adds support for the draft/account-registration extension [1].
This allows downstreams to register on upstream networks.

This will stop clients from trying to issue AUTHENTICATE requests
after connection registration.
git-svn-id: file:///srv/svn/repo/suika/trunk@725 f0ae65fe-ee39-954e-97ec-027ff2717ef4
Once the downstream connection has logged in with their bouncer
credentials, allow them to issue more SASL auths which will be
redirected to the upstream network. This allows downstream clients
to provide UIs to login to transparently login to upstream networks.
git-svn-id: file:///srv/svn/repo/suika/trunk@724 f0ae65fe-ee39-954e-97ec-027ff2717ef4
This will allow clients to properly show/hide UI to login and
register.

Implements the following recommendation from the spec:
> If the client completes registration (with CAP END, NICK, USER and any other
> necessary messages) while the SASL authentication is still in progress, the
> server SHOULD abort it and send a 906 numeric, then register the client
> without authentication.

This patch adds a bit more compliance to the chathistory IRCv3 specification.

Now that dc.nick is not blank during registration, sasl replies from the
server are correct and cap handling can be a bit simplified.

This enables production debugging of the bouncer.

We want to serve metrics via both BouncerServ and Prometheus. Add
a tiny abstraction to avoid updating multiple metrics at once.
git-svn-id: file:///srv/svn/repo/suika/trunk@709 f0ae65fe-ee39-954e-97ec-027ff2717ef4
This only exports the default metrics for now.

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.

The new upstream-user-ip directive allows bouncer operators to
assign one IP address per user.

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.
