David Goldblatt da63f23e68 HPA: Track pending purges/hugifies in the psset. 
This finishes the refactoring of the HPA/psset interactions the past few commits
have been building towards.

Rather than the HPA removing and then reinserting hpdatas, it simply begins
updates and ends them.  These updates can set flags on the hpdata that prevent
it from being returned for certain types of requests.  For example, it can call
hpdata_alloc_allowed_set(hpdata, false) during an update, at which point the
given hpdata will no longer be returned for psset_pick_alloc requests.

This has various of benefits:
- It maintains stats correctness during purges and hugifies.
- It allows simpler and more explicit concurrency control for the various
  special cases (e.g. allocations are disallowed during purge, but not during
  hugify).
- It lets allocations and deallocations avoid disturbing the purging and
  hugification orderings.  If an hpdata "loses its place" in one of the queues
  just do to an alloc / dalloc, it can result in pathological edge cases where
  very hot, very full hugepages never get hugified  (and cold extents on the
  same hugepage as hot ones never get purged).

The key benefit though is that tracking hpdatas to be purged / hugified in a
principled way will let us do delayed purging and hugification.  Eventually this
will let us move these operations to background threads, but in the short term
the benefit is that it will let us have global purging policies (e.g. purge when
the entire arena has too many dirty pages, rather than any particular hugepage).
