[usocket-devel] Patch for ABCL for IP6 and SOCKET-ACCEPT

The attached patch against usocket HEAD (basically usocket-0.5.1) address for following for ABCL: 1. GET-ADDRESS now works with underlying IP6 addresses 2. Fix SOCKET-ACCEPT to follow the documented API so that when called without an :ELEMENT-TYPE argument, use the ELEMENT-TYPE of specified in the corresponding call to SOCKET-LISTEN. With the [corresponding patches][1] this allows ABCL to run Hunchentoot. [1]: http://detroit.slack.net/~evenson/abcl/hunchentoot -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."
