Eset: Cache summary information for heap edatas.
...
This lets us do a single array scan to find first fits, instead of taking a
cache miss per examined size class.

Eset: Pull per-pszind data into structs.
...
We currently have one for stats and one for the data. The data struct is just a
wrapper around the edata_heap_t, but this will change shortly.

Use rtree tracked states to protect edata outside of ecache locks.
...
This avoids the addr-based mutexes (i.e. the mutex_pool), and instead relies on
the metadata tracked in rtree leaf: the head state and extent_state. Before
trying to access the neighbor edata (e.g. for coalescing), the states will be
verified first -- only neighbor edatas from the same arena and with the same
state will be accessed.

Use the flat bitmap for eset and psset bitmaps.
...
This is simpler (note that the eset field comment was actually incorrect!), and
slightly faster.

Eset: Parameterize last globals accesses.

Eset: take opt_lg_max_active_fit as a parameter.
...
This breaks its dependence on the global.

Extent refactor: Introduce ecache module.
...
This will eventually completely wrap the eset, and handle concurrency,
allocation, and deallocation. For now, we only pull out the mutex from the
eset.

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