Arena: share bin offsets in a global.
...
This saves us a cache miss when lookup up the arena bin offset in a remote
arena during tcache flush. All arenas share the base offset, and so we don't
need to look it up repeatedly for each arena. Secondarily, it shaves 288 bytes
off the arena on, e.g., x86-64.

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).

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

Rename extent_t to edata_t.
...
This frees us up from the unfortunate extent/extent2 naming collision.

Extents: Split out introspection functionality.
...
This isn't really part of the core extent allocation facilities. Especially as
this module grows, having it in its own place may come in handy.
