The same document may be present with different sematics under
multiple storage roots, so always reference using both ROOT_ID and
DOC_ID. This enables backends to revoke permissions for an entire
root, such as when an account is removed.
Start building provider to remember recently accessed documents.

Introduce XML metadata for storage backends, used to indicate if
custom roots should be queried, and provide any custom MIME type
icons inside that backend.
Parse metadata and resolve custom icons in UI.

Allow storage backends to publish multiple roots into the UI, which
are defined by a directory GUID, type, and label details. Update
external provider to surface a primary external storage root, and
switch to burning file path into the returned GUIDs so they remain
durable.
Added insert, update, and delete support to external provider. Adds
file extensions to display names when needed to match MIME type.
Add flags for searching and deletion, and extras for Cursor
pagination. Add directory creation dialog to UI. Opening a document
always gives write access.

"signatureOrSystem" permissions are no longer available to all apps
residing en the /system partition. Instead, there is a new /system/priv-app
directory, and only apps whose APKs are in that directory are allowed
to use signatureOrSystem permissions without sharing the platform cert.
This will reduce the surface area for possible exploits of system-
bundled applications to try to gain access to permission-guarded
operations.
The ApplicationInfo.FLAG_SYSTEM flag continues to mean what it is
says in the documentation: it indicates that the application apk was
bundled on the /system partition. A new hidden flag FLAG_PRIVILEGED
has been introduced that reflects the actual right to access these
permissions.
At some point the "system" permission category will be
renamed to "privileged".

Continuing to flesh out storage backends by adding an external
storage document backend. Still rough, but it can traverse files
and directories.
Early pass at OPEN/CREATE_DOC picker UI, which offers to traverse
any known storage backends. Supports opening subdirectories and
returning a picked file.
