Summary: Add stats tracking for eden. Thought it would be best to collect some feedback before I go ahead and add tracking for all of the operations in the "dispatcher_ops" structure.

Summary:
We still have naked pointers at the handoff to the kernel, but now
have a cleaner implementation at the level that we're going to be working at
day to day.
I also renamed `FileHandle::release` to `FileHandle::releasefile` so that it
isn't visually ambiguous with `std::unique_ptr::release` in the
`Dispatcher.cpp` code: `fh.release()` vs `fh->release()` look similar but are
dramatically different in behavior.
