libnetfs: handle dead-name notifications
Handle dead-name notifications the same way libdiskfs does. In fact, dead-name.c is a verbatim copy with trivial modifications. It clears np->sockaddr if the dead name notification was for that port. * libnetfs/dead-name.c: New file. * libnetfs/Makefile (OTHERSRCS): Add dead-name.c.
