    schemas: Add "mount-removable-storage-devices-as-read-only" option
    
    Add lockdown option to prevent the user from writing and from modifying
    files on removable storage devices. If enabled, gvfs is going to mount
    removable storage devices (i.e. flashdisks, mobile phones, cameras) as
    read-only.
