2713bcba34 Add administrative unix listen endpoint 
This adds support for listening on a Unix socket for administrative
connections, that then use a simple protocol for communicating with
the service (BouncerServ) as an administrator with a global context.

The wire format used by the Unix socket is IRC, but without
registration or overheads.

Example session:

    >>> BOUNCERSERV
    <<< 461 * BOUNCERSERV :Not enough parameters
    >>> BOUNCERSERV :n s
    <<< :gensou FAIL BOUNCERSERV :this command must be run as a user
    >>> BOUNCERSERV :u s
    <<< :gensou PRIVMSG * :marisa: 2 networks
    <<< :gensou PRIVMSG * :alice: 1 networks
    <<< :gensou BOUNCERSERV OK

a662091a9d server: fix panic stacktrace print formatting 
This change uses string formatting for the output of debug.Stack. The
output of debug.Stack is []byte, which isn't human readable.

d21fc06d88 server: cleanup user in defer 
If a user goroutine panics, this correctly removes it from the
global map instead of leaving a dangling entry behind.

the user. See [1] for motivation.

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.

d7b1c5a9a2 Allow admins to broadcast message to all bouncer users 
Typically done via:

    /notice $<bouncer> <message>

Or, for a connection not bound to a specific network:

    /notice $* <message>

The message is broadcast as BouncerServ, because that's the only
user that can be trusted to belong to the bouncer by users. Any
other prefix would conflict with the upstream network.

927ee80da1 Stop reading X-Forwarded-Port 
X-Forwarded-Port contains the destination port, not the source port,
so it isn't useful for our purposes.

Move parsing of X-Forwarded-* header fields to parseForwarded.
