Subject: Use a Device reference in PasswordSafe

Instead of wrapping an owned Device instance, PasswordSafe now only
requires a reference to a Device.  The lifetime parameter makes sure
that the device lives at least as long as the password safe.  Using a
reference instead of an owned device allows us to implement Drop on
PasswordSafe to make sure that the password safe is disabled once it is
destructed.
