OK, this turned out to be the required reading for the remainder of
the patch ;-).  Everything else was pretty much a mechanical
replacement from reftable_stack to reftable_backend, but to get rid
of the latter, we need to do this _release() thing where we used to
do the _destroy on a bare reftable_stack instance.

Looking good and understandable.
