These sys/cdefs.h are not needed. Purge them. They are mostly left-over
from the $FreeBSD$ removal. A few in libc are still required for macros
that cdefs.h defines. Keep those.

Replace use of the pipe(2) system call with pipe2(2) with a zero flags2016-06-22T21:11:27ZBrooks Davisbrooks@FreeBSD.org2016-06-22T21:11:27Zurn:sha1:b60998c6331e2be21f1fc29fa6c82d94a1f72ef0
value.
This eliminates the need for machine dependant assembly wrappers for
pipe(2).
It also make passing an invalid address to pipe(2) return EFAULT rather
than triggering a segfault. Document this behavior (which was already
true for pipe2(2), but undocumented).
