69e9b6a439 Retry on temporary net.Listener failure 
Instead of stopping to listen, retry on temporary failure. This
can happen when running out of FDs.

1c285a1b72 Fallback to alt nick 
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.

a413681253 Cancel pending commands on downstream disconnect 
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.

578020e553 Add exponential backoff when re-connecting to upstream 
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.

313c6e7f97 Add support for post-connection-registration upstream SASL auth 
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.

b5a868bbcd Abort SASL if in-progress while completing registration 
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.
