Ecache: Should know its arena_ind.
...
What we call an arena_ind is really the index associated with some particular
set of ehooks; the arena is just the user-visible portion of that. Making this
explicit, and reframing checks in terms of that, makes the code simpler and
cleaner, and helps us avoid passing the arena itself all throughout extent code.
This lets us put back an arena-specific assert.

Unify extent_alloc_wrapper with the other wrappers.

Previously, it was really more like extents_alloc (it looks in an ecache for an
extent to reuse as its primary allocation pathway). Make that pathway more
explciitly like extents_alloc, and rename extent_alloc_wrapper_hard accordingly.

Arena: Loosen arena_may_have_muzzy restrictions.

If there are custom extent hooks, pages_can_purge_lazy is not necessarily the
right guard. We could check ehooks_are_default too, but the case where
purge_lazy is unsupported is rare and getting rarer. Just checking the decay
interval captures most of the benefit.
