Based on a patch from Andrew Wansink, this change adds an open socket

In this context a "socket" is a UNIX domain socket, aka a named pipe.
This is useful
because -u socketname is supported for PMDAs and dbpmda previously
could not use/exercise this
it is sometimes easier to debug a pmda by running it from within
a debugger with a -u socketname option where it will hang waiting
for pmcd/dbpmda and then running dbpmda in another window
