MFC r182193:
Implement WNOWAIT flag for wait4(2). It specifies that process whose status
is returned shall be kept in the waitable state.
Add WSTOPPED as an alias for WUNTRACED.

MFC r182424 (by davidxu):
Don't remove queued SIGCHLD if options contain WNOWAIT, so other
threads still can be notified by the signal.
