... the storage list view
1. Change to ExternalStorageProvider
When available volumes have changed, it now notifies on
"content://com.android.externalstorage.documents" rather than on
"content://com.android.externalstorage.documents/root/", because it'll also
affect "content://com.android.externalstorage.documents/document/*/children".
2. Change to DocumentUI
- DirectoryLoader now won't crash when a provider returns null.
- DirectoryFragment now closes itself (i.e. emulate a back press) when a load
failed.
- It now correctly reloads contents when a volume is ejected thanks to 1.

Per UX, default strings should have space between value and units
resulting in "12.3 GB". Add a formatting variant that returns the
various components for callers who want to build their own strings.
For now there is only one mounted emulated volume at a time, and
it's always the primary storage, so give it the default rootId to
keep old Uris working.

Move code for checking file extensions and MIME types from
ExternalStorageProvider into android.os.FileUtils, so it can be used by
other clients (e.g. DownloadsProvider).

Send limited broadcast intent when certain volume state changes
occur; the only customer for now is ExternalStorageProvider.
Change notification flow to be less bumpy. Pick USB icon based on
disk type, and avoid using "generic" disk labels.

Adds logic to ExternalStorageProvider to scan non-visible volumes,
such as USB OTG devices. We use internal paths when surfacing these
volumes, which also optimizes around the FUSE daemon for public
devices. Also dumps internal state when requested.
VolumeInfo now directly contains DiskInfo, which means it's
snapshotted when sending events, avoiding teardown races. Switch
notifications to use this DiskInfo directly.
Finish wiring up new volume state, including helper methods to make
it readable/writable state clearer. Handle disks and volumes with
spaces in their labels.

Roots use a flag to indicate they have settings, and DocumentsUI
offers to launch towards someone who handles a new Settings intent.
Slight rename of browse intent for clarity.

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.
