Include volume UUID in generated document IDs to uniquely identify
volumes over time. Show volume label to users. Watch for mount
changes to update available roots.

For the new documents work, we're only interested in the subset of
ContentProviders that actually implement DocumentsContract. Instead
of returning all providers, add <intent-filter> support to make it
easier to limit the set of returned ProviderInfo.
Define a well-known action for DocumentsProviders, and start using it
when querying for roots. Continue supporting the old <meta-data>
approach until all apps have been updated.

A provider can include extras in their Cursors to indicate that
loading is ongoing, or include an error or informational message,
which are now shown in footer views.
Fix registration to always get change notifications.
Test provider that verifies common provider behavior of holding
a reference to "cloud" resources that are released by GC when the
remote Cursor is closed. Also used to validate Recents behavior
for slow providers.

Using a contract class requires that a provider implement it exactly
with little help. This change introduces a DocumentsProvider abstract
class that provides a client-side implementation of the contract that
greatly reduces developer burden, and improves correctness.
This also moves to first-class DocumentRoot objects, and moves calls
with complex side effects to be ContentProvider.call() invocations,
offering more granular permission control over Uri operations that
shouldn't be available through Uri grants.
This new design also relaxes the requirement that root information be
burned into every Uri. Migrate ExternalDocumentsProvider and
DocumentsUI to adopt new API.

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.

When requesting thumbnails, check if their dimensions are larger
than requested, and downscale to avoid memory pressure. Load them
async and with LruCache.
Extend MatrixCursor so that RowBuilder can offer() columns without
requiring they know the projection map. This makes it easier to
respond to query() calls, where the remote side controls the
projection map. Use it to handle custom projections in external
storage backend.
Update date/time formatting to match spec.

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.

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.
