* sysdeps/mach/hurd/socketpair.c (__socketpair): Renamed from socketpair. Made socketpair a weak alias. * sysdeps/mach/hurd/pipe.c (__pipe): Reimplemented using __socketpair. Use S_IFIFO protocol to make pipes POSIX conforming, but fall back on the old protocol if the socket server doesn't support it. * include/sys/socket.h: Add prototype for __socketpair.
