        src/lib/libc/sys: mknod.2
        src/sys/compat/netbsd32: netbsd32_netbsd.c

        src/tests/lib/libc/c063: t_mkfifoat.c
        src/tests/lib/libc/sys: t_mkfifo.c

Log Message:
Add mkfifo{,at}(2) mode in mknod{,at}(2) as requested by POSIX

mknod with mode & S_IFIFO and dev=0 shall behave like mkfifo.

Update the documentation to reflect this state.

Add ATF tests.

This is an in-kernel implementation as typically user-space programs use
mkfifo(2) directly, however whenever there is need to bypass libc (like in
valgrind) then portable POSIX software calls the mknod syscall.
