Subject: [PATCH 30/41] Monitor, Incremental: use device policies
spare_criteria is expanded to contain policies which will be generated
by handler's get_spare_criteria() function. It provides a way to
test device for metadata specific policies earlier than during
add_do_super(), when device is already removed from previous
array/container for Monitor.
For Incremental, it ensures that all criteria are tested when trying
spare. It is not tested when device contains valid metadata.
