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.

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

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

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).

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.

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

Emap: Standardize naming.
...
Namespace everything under emap_, always specify what it is we're looking up
(emap_lookup -> emap_edata_lookup), and use "ctx" over "info".

Emap: Remove direct access to emap internals.
...
In the process, we do a few local cleanups and optimizations. In particular,
the size safety check on tcache flush no longer does a redundant load.

Make jemalloc.c use the emap interface.
...
While we're here, we'll also clean up some style nits.

Emap: Move in iealloc.
...
This is logically scoped to the emap.

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.

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

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

Tell edatas their creation arena immediately.

This avoids having to pass it in anywhere else.
