[PATCH 6/8] Handle notification for all-stop.

[Yao Qi <yao@codesourcery.com>]

Now, it is possible to get notifications in all-stop mode, so we
should use 'getpkt_or_notif_sane' instead of 'getpkt_sane'.  Beside
this, once a notification arrives, GDB will return to core as this
event is not interesting and keep waiting back again.

gdb:

	* remote.c (remote_wait_as): Call 'getpkt_or_notif_sane' instead
	of 'getpkt_sane'.
	Return minus_one_ptid early if gets a notification.
