ssnet: throw a nicer-looking Fatal when the mux connection dies.
...
When it happens, it's probably because the client died and the server hasn't
noticed yet.

Whoops, we were spinning in the server when the mux outbuf was full.
...
Once again, the buffering gets mixed up with the selecting. Seems to be the
story of my life.

More latency fixes: use a PING/PONG pair to limit queue length.
...
It seems ssh is kind of stupid and uses a really big SO_SNDBUF (hundreds of
kbytes). Thus, we can't depend on the socket's output buffer to limit our
latency down to something reasonable. Instead, limit the amount of data we
can send in a single round trip.

Don't overfill the mux's output buffer.
...
Otherwise a single busy stream can ruin it for everybody.

Do non-blocking connect().
...
This way we don't freeze the entire proxy when someone tries to connect to a
nonexistent IP address (oops).

Add a -v (and -vv) flag and decrease default message verbosity.

Clean up SockWrapper.peername stuff.
...
Some fds don't have peernames, and sometimes the peername isn't very
helpful, so let's fill it in by hand when appropriate.

Improve some debugging information to find the weird data problem.
...
Turns out list.pop() removes the *last* item, not the first one. Oops. It
all works great for queues of only one item... :)

We now have a server that works... some of the time.
...
There still seem to be some weird timing and/or closing-related bugs, since
I can't load the eqldata project correctly unless I use --noserver.

stdin and stdout have different fds, so make SockWrapper take *two* socks.
...
We'll need this when we have a SockWrapper pointing at a Mux on a subprocess
pipe.

Basic implementation of a multiplex protocol - client side only.
...
Currently the 'server' is just a pipe to run 'hd' (hexdump) for looking at
the client-side results. Lame, but true.

Move some code that'll be useful for the server into ssnet.py.
