* sysdeps/unix/sysv/linux/bits/waitflags.h
	(WSTOPPED, WEXITED, WCONTINUED, WNOWAIT): New macros.
	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_WAITID_SYSCALL):
	New macro.
	* sysdeps/unix/sysv/linux/waitid.c: New file.  Use new syscall when
	available, or fall back to the waitpid-based generic code.
