ae23e5f426 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.

bb70df8e5b 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.

a7862df616 Rename extent_t to edata_t.
This frees us up from the unfortunate extent/extent2 naming collision.

403f2d1664 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.

92a511d385 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.
