[usocket-devel] Support for UNIX sockets

[Chun Tian (binghe)]

Good, new feature come in again.

Maybe that's USOCKET's next goal after UDP support. I think new  
usocket classes should be created to support them, or just make  
AF_INET as a option when create new socket to let user choose AF_LOCAL  
instead.
