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).
