* target.h (TARGET_WNOHANG): New.

	* target.c (target_wait): Add `options' argument.  Adjust.
	(struct target_ops) <to_wait>: Add `options' argument.
	(target_wait): Add `options' argument.
	* infrun.c (wait_for_inferior): Pass 0 as options to
	target_wait (blocking wait).
	(fetch_inferior_event): Pass TARGET_WNOHANG as options to
	target_wait.
	* fork-child.c (startup_inferior): Pass 0 as options to
	target_wait (blocking wait).
	* linux-nat.c (linux_nat_create_inferior): Remove async masking.
	(linux_nat_wait_1): Add `target_options' argument.  Use it instead
	of checking on target_can_async_p.
	(linux_nat_wait): Add `target_options' argument.  Adjust.
	* remote.c (remote_wait_ns): Add `options' argument.  Adjust to
	check on TARGET_WNOWAIT instead of checking on remote_is_async_p.
	(remote_wait_as): Add `options' argument.  Adjust to check on
	TARGET_WNOWAIT instead of checking on remote_is_async_p.  If doing
	a blocking wait, keep waiting until an interesting event comes
	out.
	(remote_wait): Add `options' argument.  Don't loop here if the
	target is in async mode, and a blocking wait has been requested.

	* top.c (deprecated_target_wait_hook): Add `options' argument.
	* linux-thread-db.c (thread_db_wait): Add `options' argument, and
	pass it down to the layer beneath.
	* inf-ptrace.c (inf_ptrace_wait): Add `options' argument.
	* record.c (record_beneath_to_wait): Add `options' argument.
	(record_wait): Add `options' argument, and pass it down to the
	layer beneath.
	* bsd-uthread.c (bsd_uthread_wait): Add `options' argument.
