Add pipe2() system call.
The pipe2() function is similar to pipe() but allows setting FD_CLOEXEC and O_NONBLOCK (on both sides) as part of the function. If p points to two writable ints, pipe2(p, 0) is equivalent to pipe(p). If the pointer is not valid, behaviour differs: pipe2() writes into the array from the kernel like socketpair() does, while pipe() writes into the array from an architecture-specific assembler wrapper.
