Combines related columns and constants onto the same class so they
are easier to discover. Move back to surfacing roots with columns
so they are consistent with documents.
Advanced roots are represented with a flag instead of distinct
types. Flags to indicate supporting of well-known media types,
instead of arbitrary an MIME filter. Reintroduce well-formed rootId
to support recents.
Always use the expanded version of "documents" in constants, methods,
and argument names.
Refactor DocumentProvider method names to clearly distinguish if
a single item or multiple could be returned, and of which type. Add
documentation to clearly define which methods have already been
overridden.

Create documents manage mode to support Downloads and transient
storage devices. Locks user into requested backend root, and forces
file sizes on and sorting by last modified.
Separate API constants for Documents versus Roots, and give concrete
MIME types for roots.
Treat null sizes as unknown. Documents are always enabled in list
so that divider is drawn. Mark external storage file as writable.

Show recent directories in a separate fragment, and save as serialized
versions of new DirectoryStack. Cleaner behavior around recents and
search, instead of treating them as pseudo-Documents.
More uniform item layouts between list and grid, including both date
and size information, and originating storage root in recents. Avoid
clashing directory loaders by assigning unique numbers. Promote
list/grid switching up into activity.

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.
