When creating or renaming files on external storage, sanitize the
requested display names to be valid FAT filenames. This also fixes
a handful of directory traversal bugs.
Also relax logic around generating display names to allow any
extension which maps to the requested MIME type. Tests to verify.

Some mounted storage volumes may not have a user-defined label. In
those cases, use the default description for the volume.

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.

Also always lower-case extension to extract MIME type correctly,
we may want to fix in MimeUtils at some point.

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.

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.
