Migration of MIME type resolution, DRM handling.

Since MediaFile is a hidden API, migrate it's logic inside the
MediaProvider boundary.  Add tests for file name and extension
extraction.

When we detect a DRM file, ask DrmManagerClient to help resolve the
actual underlying MIME type.  Then proceed with a normal scan, since
MediaMetadataRetriever already knows how to extract metadata from
DRM files.

Fix some hidden API annotations.
