The worst of the name length limitations can be worked around by
opening the directory where the socket is to go as a file
descriptor, then using /proc/self/fd/<fd>/<basename> as the name
of the socket.  This technique also works with "connect" and in
other contexts where a struct sockaddr is needed.  At first
glance, it looks like your patches only help with "bind".
