Stephen Smalley e13fabd75a Label /data/media with its own type and allow access.
/data/media presently is left in system_data_file, which requires
anything that wants to write to it to be able to write to system_data_file.
Introduce a new type for /data/media, media_rw_data_file (to match
the media_rw UID assigned to it and distinguish it from /data/misc/media
which has media UID and media_data_file type), and allow access to it.

We allow this for all platform app domains as WRITE_MEDIA_STORAGE permission is granted
to signature|system.  We should not have to allow it to untrusted_app.

Set up type transitions in sdcardd to automatically label any directories
or files it creates with the new type.
