[PATCH 6/7] Cleanup pending queues before resume in all-stop

[Yao Qi <yao at codesourcery dot com>]

In patch 3/N, we mark 'remote_async_get_pending_events_token'
only in non-stop mode, and function 'remote_notif_process' is
called in async event handler accordingly.  In all-stop mode,
we need to find a place to call 'remote_notif_process', I find
it is reasonable to process them before resume inferior.  So
this is what this patch does.

	* remote.c (remote_resume): Call 'remote_notif_process' in
	all-stop mode.
