- Implement pipe2 syscall for Linuxulator. This syscall appeared in 2.6.27

but GNU libc used it without checking its kernel version, e. g., Fedora 10.
- Move pipe(2) implementation for Linuxulator from MD files to MI file,
sys/compat/linux/linux_file.c.  There is no MD code for this syscall at all.
- Correct an argument type for pipe() from l_ulong * to l_int *.  Probably
this was the source of MI/MD confusion.
