Tcache fluhing: increase cache miss parallelism.
...
In practice, many rtree_leaf_elm accesses are cache misses. By restructuring,
we can make it more likely that these misses occur without blocking us from
starting later lookups, taking more of those misses in parallel.

Tcache flush: Add an emap "batch lookup" path.
...
For now this is a no-op; but the interface is a little more flexible for our
purposes.

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".

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.

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.
