1ed7ec369f Emap: Add emap_assert_not_mapped.
The counterpart to emap_assert_mapped, it lets callers check that some edata is
not already in the emap.

e034500698 Edata: rename "ranged" bit to "pai".
This better represents its intended purpose; the hugepage allocator design
evolved away from needing contiguity of hugepage virtual address space.

eda9c2858f Edata: zero stack edatas before initializing.
This avoids some UB. No compilers take advantage of it for now, but no sense in
tempting fate.

79ae7f9211 Rtree: Remove the per-field accessors.
We instead split things into "edata" and "metadata".

bb6a418523 Emap: Drop szind/slab splitting parameters.
After the previous diff, these are constants.

294b276fc7 PA: Parameterize emap. Move emap_global to arena.
This lets us test the PA module without interfering with the global emap used by
the real allocator (the one not under test).

12eb888e54 Edata: Add a ranged bit.
We steal the dumpable bit, which we ended up not needing.

a0c1f4ac57 Rtree: take the base allocator as a parameter.
This facilitates better testing by avoiding mixing of the "real" base with the
base used by the rtree under test.

7013716aaa Emap: Take (and propagate) a zeroed parameter.
Rtree needs this, and we should really treat them similarly.

1d449bd9a6 Emap: Internal rtree context setting.
The only time sharing an rtree context saves across extent operations isn't a
no-op is when tsd is unavailable.  But this happens only in situations like
thread death or initialization, and we don't care about shaving off every
possible cycle in such scenarios.

08eb1e6c31 Emap: Comments and cleanup
Document some of the public interface, and hide the functions that are no longer
used outside of the emap module.

231d1477e5 Rename emap_split_prepare_t -> emap_prepare_t.
Both the split and merge functions use it.

040eac77cc Tell edatas their creation arena immediately.
This avoids having to pass it in anywhere else.
