ipc command & native control interface

[jrhea]

This PR simply packages the libp2p-dameon as a shared object and exposes a simple native control interface with two methods:

• startDaemon(config)
• stopDaemon()

The control interface is still managed via IPC

Build Instructions:

# build everything
$ make all
# build go daemon
$ make deps && make go-daemon
# build java daemon
$ make deps && make java-daemon
# only build the daemon control shared object 
$ make deps && make daemon-control-so

Run the daemon from Java

$ cd bindings && java p2pd
Control socket: /tmp/p2pd.sock

Can this be merged into the base branch?

I see no reason why not to, and @vyzo has already LGTM’d. As we continue hacking on this, there’ll be opportunities to revisit if needed. I’ll just go ahead and merge.

Sorry for the delay – Santa and the Three Wise Kings called.

@jrhea – this looks pretty good \o/

We can close #28, as that former PR is now being splintered according to the plan, right?

[raulk]

Nice one for an orderly shutdown.

Eventually I'd like us to bring in some grouping/organisation to the daemon config, but definitely not a showstopper here. See related: #35.
