Parially, a patch from Scott McKellar:

1. In socket_open_unix_server() and socket_open_unix_client(), I added
checks to make sure that the path parameter doesn't point to aomething
too big to fit into the receiving buffer of the struct sockaddr_un.

2. In _socket_handle_client_data() I add a terminal nul to the data
received by recv().

Also, reversing the semantics and default of NDEBUG per.  To turn on debugging
code, set DEBUG to 1 durring the build:

 $ DEBUG=1 make clean all
