Framework to add support for unix socket protocol

[ghost]

Sort of awkwardly worded title; right now, I would like to be able to use a unix socket to proxy an Iron server through another HTTP server. I know that such an extension is possible, because the crate hyperlocal exists to add Unix socket support to Hyper. Unix sockets are beneficial because they can have permissions to only be read by certain processes.

I'm not 100% sure that the Iron framework would support this as a plugin, because the protocol is currently fixed to just HTTP and HTTPS, as far as I'm aware. If it would be possible to add support to extend this protocol, a plugin could be made to modify Iron to use Unix sockets instead of just TCP.

You can now provide an arbitrary Hyper Listener to Iron - does that cover this feature request?

@sfackler could you provide an example about how to use a Listener? I'm also trying to use an unix socket with Iron, but I'm stuck

When 0.7 is released you should be able to use hyperlocal and mount iron as service creator.
