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.

Also document that rootIds need to be stable, so removable media
roots should use the media serial number.

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.

directories are now always enabled. Also unifies enabled testing.

When a file already exists on disk, try adding a counter suffix to
make a unique name. Move services near top of roots list, just below
recents. Remove "Documents" root.
Increase number of recents allowed from single provider, and add more
logging to diagnose wedged loaders.
When launching GET_CONTENT apps, wait for successful result before
relaying result; canceled requests now return to DocumentsUI.
Add CloseGuard to ContentProviderClients, since leaked instances can
keep the remote process alive.
Fix UI bug around trailing breadcrumbs. Fix bug that dropped Recents
from roots list. Add up action to Settings activity. Give our
activity a default icon while waiting for async roots to load.

Move all RootInfo queries to background threads to avoid janking
the UI. Update passes happen on spawed task, which swaps out updated
cache results when finished. Support partial updates when only a
single package/authority has changed. Watch for change notifications
for roots, since flags can change over time.
Ignore stopped packages when in background, but query them for roots
when launching any picker UI.
Optimize management launches by treating as one-shot requests that
don't need to wait for all RootInfo.

Documents searches now happen root-wide, instead of only under a
subdirectory. Updates abstract class and flags to match. Add flag
for a root to indicate it's empty, and hide empty roots in UI unless
creating.
Define "Documents" public directory and storage backend to contain
files.

to avoid crashing DocumentsUI.

Hide non-finished downloads from normal picker UI, but keep them
around in management mode. Uses a Uri query parameter and a hidden
API on DocumentsProvider.
Scale thumbnails to fit viewport, always show MIME icon while waiting
on thumbnails, and crossfade between them. Cancel thumbnail tasks
when views are recycled.
Filter directories out of search results for now. Also leave sort
ordering from backend intact, since it's custom ranking. Fix
SearchView interaction to dismiss properly and restore across
orientation and drawer state changes.
Hide most actions when drawer is open. Invalidate RootInfo cache
when locale changes. Apply sort ordering when showing recent create
directories. Hide recent summary string when icon is enough for user
to disambiguate.
