Unify extent_alloc_wrapper with the other wrappers.
...
Previously, it was really more like extents_alloc (it looks in an ecache for an
extent to reuse as its primary allocation pathway). Make that pathway more
explciitly like extents_alloc, and rename extent_alloc_wrapper_hard accordingly.

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.

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.

Make extent module hermetic.
...
In the form of extent2.h. The naming leaves something to be desired, but I'll
leave that for a later diff.
