add taskqueue_drain_all

This API has semantics similar to that of taskqueue_drain but acts on
all tasks that might be queued or running on a taskqueue.
A caller must ensure that no new tasks are being enqueued otherwise this
call would be totally meaningless.  For example, if the tasks are
enqueued by an interrupt filter then its interrupt must be disabled.
