Clean up some permissions.

Note that WRITE_OWNER_DATA and READ_OWNER_DATA don't actually appear
to be associated with anything or used by anyone, so they are just
deleted.

Also deprecate the activity API to go in the foreground.  I didn't
realize that was released in the SDK.  It needs to go away.
