b3df80bc79 Pull HPA options into a containing struct. 
Currently that just means max_alloc, but we're about to add more.  While we're
touching these lines anyways, tweak things to be more in line with testing.

ca30b5db2b Introduce hpdata_t. 
Using an edata_t both for hugepages and the allocations within those hugepages
was convenient at first, but has outlived its usefulness.  Representing
hugepages explicitly, with their own data structure, will make future
development easier.

Previously, we replicated the logic in hpa_supported in the test as well.

43af63fff4 HPA: Manage whole hugepages at a time. 
This redesigns the HPA implementation to allow us to manage hugepages all at
once, locally, without relying on a global fallback.
