  (NI 6020E, NI PXI-6040E, NI 6052E, NI 6062E, NI 6070E/6071E, and
  PCI-MIO-16E-4 Devices Only) You can connect each DAC to the device
  internal reference of 10 V or to the external reference signal
  connected to the external reference (AO EXT REF) pin on the I/O
  connector. This signal applied to EXT REF should be within
  ±11 V. You do not need to configure both channels for the same mode.

So RF_EXTERNAL is a valid unit (i.e. in units of the AO EXT REF
signal).  The next commit will add this unit.

For example, the newly fixed pypiezo.config.ChannelConfig [4] uses the
AREF enum values as possible choices for it's `analog-reference`
setting.  h5config makes deepcopies of mutable objects to avoid
confusion if the mutable is changed externally.  It then compares the
deepcopies with uncopied values.  Now that deepcopying works for
_NamedInts, the h5config behavior will work.
