Revamp the sequences for suspend/hibernate -> resume so that the code

paths are reflexive.  It is now possible to fail part-way through a
suspend sequence, and recover along the resume code path.
Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used
after hibernate (and suspend too) to finish the job.  Some drivers
must be converted at the same time to use this instead of shutdown hooks
(the others will follow at a later time)
