Implement EXTRA_HAS_MORE and EXTRA_REQUEST_MORE contract with
document providers. Providers can include EXTRA_HAS_MORE when
additional data is available with additional cost, such as a network
request.
Listen to content changes based on returned cursor instead of
original Uri. Include a test backend to exercise. UX still under
development.

Update DirectoryFragment to render List<Document>, making it more
general purpose. Feed it documents either from a backend Cursor or
after resolving fields from a recents Cursor. Start in recents when
no persisted stack available. Synthesize a root for recents.
Local directory filtering and sorting using predicates and
comparators, all performed on background thread. Introduce
UriDerivativeLoader which handles ContentObserver updates while
producing a derivative work of a Cursor.
Split data model classes into separate files.
