Add Downloads.Impl.COLUMN_MEDIASTORE_URI & DownloadColumns.Description.
Entries from DownloadProvider are added to MediaStore Downloads
collection. COLUMN_MEDIASTORE_URI will be used to track corresponding
entries in MediaProvider. We can't re-use COLUMN_MEDIAPROVIDER_URI
for this purpose because it is updateable by apps.
