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.

Namespace everything under emap_, always specify what it is we're looking up

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.

Rework the bin locking around tcache refill / flush.
...
Previously, tcache fill/flush (as well as small alloc/dalloc on the arena) may
potentially drop the bin lock for slab_alloc and slab_dalloc. This commit
refactors the logic so that the slab calls happen in the same function / level
as the bin lock / unlock. The main purpose is to be able to use flat combining
without having to keep track of stack state.
In the meantime, this change reduces the locking, especially for slab_dalloc
calls, where nothing happens after the call.

Disallow merge across mmap regions to preserve SN / first-fit.
...
Check the is_head state before merging two extents. Disallow the merge if it's
crossing two separate mmap regions. This enforces first-fit (by not losing the
SN) at a very small cost.

NetBSD specific changes:
...
- NetBSD overcommits
- When mapping pages, use the maximum of the alignment requested and the
compiled-in PAGE constant which might be greater than the current kernel
pagesize, since we compile binaries with the maximum page size supported
by the architecture (so that they work with all kernels).
