Title: Added support for unix domain sockets

This is only implemented for GCDAsyncSocket.

Xcode/DomainTest/ demonstrates the use of unix domain sockets as a server and a client.

I tried to implement this feature with as little overall changes to the code as possible, which has yielded some additional code replication.
