Currently all document roots represent MTP storage, but we will not have
this assumption after starting show MTP devices (not storage) as
document roots.
To distinguish these two types of roots, the CL adds document type
column to the document table in MtpDatabase.

When the provider is created, it reopens MTP devices that are recorded
in the database. It enables the provider to resume MTP session after the
provider process is killed by the system.

MTP identifiers like object handle is unstable over MTP sessions. The
CL introduce two methods to MtpDatabase that enables the provider to
remap exisitng document ID with new MTP identifiers when the provider
reopen the MTP session.
* MtpDatabase#clearMtpIdentifier invalidates old MTP identifiers
* MtpDatabase#resolveRootDocuments remaps invalidated documents with
new MTP identifier.

If the remote MTP device is backed by typical file system, the file name
is unique among files in a directory. However, MTP protocol itself does
not guarantee the uniqueness of name so we cannot use fullpath as ID.
Instead of fullpath, we use artifical ID generated by MtpDatabase
itself. So we don't need to store fullpath in the database.
