Cleans up API so it consistently refers to opening or working with a
subtree of documents. Also separates isChildDocument() support from
the concept of directory tree selection.

DocumentsProviders can mark documents as supporting rename, and they
have the opportunity to change the DOCUMENT_ID as a side effect of
the rename. This supports providers that embed the display name
into DOCUMENT_ID. Issues a URI permission grant to the new document,
if any.
Adds renaming support to platform ExternalStorageProvider. Also
adds directory deletion support.

Introduce new ACTION_PICK_DIRECTORY that allows users to grant access
to an entire document subtree. Instead of requiring grants for each
individual document, this leverages new prefix URI permission grants
by defining new "via"-style URIs:
content://com.example/via/12/document/24/
This references document 24 by using a prefix grant given for
document 12. Internally, we use isChildDocument() to enforce that
24 is actually a descendant (child, grandchild, etc) of 12. Since
this is an optional API, providers indicate support with
Root.FLAG_SUPPORTS_DIR_SELECTION.
Extend DocumentsUI to support picking directories. Expose
createDocument() API to work with returned directories.
Offer to canonicalize via-style URIs into direct URIs, generating
exact permission grants along the way. Override openAssetFile()
to pass through CancellationSignal. Move testing code into ApiDemos.

While user is actively looking at a directory, subscribe to inotify
events and notify of content changes to trigger requeries. Reference
count the observers, since multiple cursors are regularly open during
requeries.
Fix leaking cursors on activity rotation; crazy loader ID generation
is no longer needed.

AssetFileDescriptor augments a ParcelFileDescriptor with details
about how it should be interpreted, so extend it to support a Bundle
of extras. Then use these extras to share thumbnail orientation
metadata.
The raw image data of EXIF thumbnails matches the orientation of
the enclosing image, but the thumbnail data doesn't repeat the EXIF
flags. This meant that receivers of openDocumentThumbnail() would
get an image that needed to be transformed, but without enough
context to actually transform it.
Instead of transforming and recompressing the image on the fly on
the provider side, send a transformation hint that the receiver
side can interpret.

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.

All background work is going through AsyncTasks, which uses a shared
thread pool. Even with the new ContentProviderClient logic to detect
ANRs, the UI can still appear to be unresponsive for 20 seconds, even
if the user attempted to switch to a different backend. In the worst
case, a backlog of thumbnail requests would end up wedging Loaders
for a long time, since they all share the same THREAD_POOL_EXECUTOR.
This change isolates calls to each provider onto their own thread,
which they're free to wedge and recover from over time.
It also means we no longer need a dedicated thread pool for recents
loading, and can use a simpler Semaphore instead.
Disables thumbnails in recents on svelte devices.

All ContentProvider calls are currently blocking, making it hard for
an app to recover when a remote provider is wedged. This change adds
hidden support to ContentProviderClient to timeout remote calls,
treating them as ANRs. This behavior is disabled by default.
Update DocumentsUI to use a 20 second timeout whenever interacting
with a storage provider.

Yet another iteration from UX on how roots should be ordered. Since
we no longer categorize by type, remove from public API. Updated
asset drop with new dividers.
Update public API docs to be explicit about required columns. Hide
flags and columns that aren't required for third-party apps.
Move remainder of potentially blocking work to AsyncTasks, including
creating directories, picked root resolution, and creation of new
documents once picked.
Improve performance of layouts by removing baseline alignment and
reduce hierarchy depth. Set alpha on ImageViews directly to avoid
offscreen rendering hit.
Limit returned recents to 45 days. Show load in recents when still
waiting for backends. Show empty message when no recents stacks to
create from. Use unique key when saving recent stacks.
