Previously MtpDocumentsProvider#queryDocument returned
FLAG_DIR_SUPPORTS_CREATE for device having multiple storages.
This was wrong because if the device has multiple storages,
MtpDocumentsProvider places the storages under the device document, thus
users cannot create a document just under the device document.

Prevously MtpDocumentsService was started as background service, then it
turns into a foreground service by calling Service#startForeground.
The workflow did not work until this, because now background activity
cannot launch a background service.
The CL starts using NotificationManager#startForegroundService to launch
MtpDocumentsService so that the service can be started as foreground
service directly.

The structure of files in MtpDocumentsProvider looks like
/device/storage/files. But MtpDocumentsProvider shows files
just under the device if the device has only single storage.
It causes a problem that MtpDocumentsProvider tries to create a file
under the device. Previously it tries to create a file with storageId =
0, which means MTP device choose a storage to store the file.
Because it only happens when the device has a single storage, the file
is properly written to the device. But the database in
MtpDocumentsProvider goes into the illegal state where the file is
placed just under the device.

When deleting files, MtpDocumentsProvider clears LoadingTask in
DocumentsLoader to update directory contents list. Previously it can
clear ongoing task, and it skips calling Mapper#stopAddingDocuments.
Since Mapper#startAddingDocuments and Mapper#stopAddingDocuments must be
called 1 to 1, it causes precondition check failure at the next call of
Mapper#startAddingDocuments.

Fix: 28076320
Previously MtpDocumentsProvider used pipes to transfer bytes from an
application to the provider when writing a document. The problem was
application could not ensure that the last chunk of bytes was
successfully written to MTP device, since pipes had been already closed
when the provider transferred bytes to MTP device. Though the provider
encountered an error, the provider could not report the error to an
application.
The CL switches the method to transfer bytes from pipes to AppFuse. Now
application can flush() bytes on the file descriptor, and flush will not
complete until the provider completes writing bytes to MTP device.

To open files by using AppFuse, the provider needs to know the size of
file. Previously we cannot open 4G+ files because we cannot obtain file
size for such large files.
Now MtpDatabase contains correct size for 4GB+ file size. The CL starts
opening files by using AppFuse which obtains partial bytes by using
getObjectPartial64 operation.

MtpObjectInfo contains object size as 32-bit integer and the provider
needs to invoke MtpDevice#getObjectSizeLong hidden API to get 64-bit
object size.
The CL switches to use MtpDevice#getObjectSizeLong hidden API if
MtpObjectInfo#getCompressedSize() returns 0xffffffffL, which means the
object size is more than 4GB.

(cherry picked from commit 35693da25a)
If we have an existing file in the destination directory, which has the
same name with the source file, adding suffix number is
DocumentsProvider's responsibility.
Because MTP does not provide a way to check existance of files with
given name, the logic is implemented as try-and error strategy. The CL
lets If we MtpDocumentsProvider assume we have a file that shares the
same name with the source file if it failed to invoke
MtpDevice#sendObjectInfo. In this case MtpDocumentsProvider retry to
invoke sendObjectInfo with new name with suffix number.

Previously if DocumentsProvider found timeout when terminatnig
RootScanner's background thread, it just output it in error log. Thus
the timeout is not regarded as an error in MtpDocumentsProviderTest, and
it makes flaky PipeManagerTest which runs just after
MtpDocumentsProviderTest.
The CL
* lets MtpDocumentsProvider throw TimeoutException for timeout.
* removes redundant resumeRootScanner calls to avoid timeout of
RootScanner#pause.
Also the CL did cleanup the logic that pauses RootScanner when we don't
find any devices. Previously the logic was in
MtpDocumentsProvider#closeInternal but it is not efficient because we
invokes RootScanner#resume just after
MtpDocumentsProvider#closeInternal. Now the CL moves the logic to
RootScanner so that it can pause itself automatically.

Once MTP device is disconnected from Android, the files on MTP device
are marked as 'DISCONNECTED' in metadata database. These metadata will
be back when MtpDocumentsProvider finds the reconnected MTP device and
fetches the files again.
Previously the 'DISCONNECTED' files are not automatically
refetched. User needs to see files in Documents UI again to reuse
document ID of 'DISCONNECTED' files. The CL changes DocumentLoader so
that it automatically refetches disconnected documents.

The MTP spec does not offer a way to update bytes of exisitng files, so
our provider implementation creates a new file with new bytes and
removes old one.
Previously the new file uses new document ID and the exising document ID
is expired. Also the provider does not update the metadata
database. Thus users see the old flie in DocumentsUI but actually the
files is not accessible.
The CL updates the database with exisitng document ID, so that we can
access the new file with exisiting document ID.

mapping.

When device has multiple storages, storage are shown as directory under
the device root. In this case, we would not like to add device name to
storage.

The tree structure of MTP model looks like /device/storage/objects. But
almost all MTP device has only single storage, so it's redundant to show
a single storage as a child of device in UI.
MtpDocumentsProvider has a special logic to skip single storage, and
shows storage's object as a children of device in such case. Previously
the logic was applied when MtpDocumentsProvider returned a root
list. The provider returns a storage as a Documents.Root, instead of
device if the device has only one storage.
However the number of root cannot be obtain for closed device. Thus the
previous logic did not work for closed devices that have a single
storage. The CL moves the logic from queryRoot to
queryChildDocuments. Now MtpDocumentsProvider always returns a device as
root, then it returns storage's objects as the device's children, where
we has already opened the device.
