David Goldblatt 0f6c420f83 HPA: Make purging/hugifying more principled. 
Before this change, purge/hugify decisions had several sharp edges that could
lead to pathological behavior if tuning parameters weren't carefully chosen.
It's the first of a series; this introduces basic "make every hugepage with
dirty pages purgeable" functionality, and the next commit expands that
functionality to have a smarter policy for picking hugepages to purge.

Previously, the dehugify logic would *never* dehugify a hugepage unless it was
dirtier than the dehugification threshold.  This can lead to situations in which
these pages (which themselves could never be purged) would push us above the
maximum allowed dirty pages in the shard.  This forces immediate purging of any
pages deallocated in non-hugified hugepages, which in turn places nonobvious
practical limitations on the relationships between various config settings.

Instead, we make our preference not to dehugify to purge a soft one rather than
a hard one.  We'll avoid purging them, but only so long as we can do so by
purging non-hugified pages.  If we need to purge them to satisfy our dirty page
limits, or to hugify other, more worthy candidates, we'll still do so.
