  Improved mapping of extension states from combined device states.

  This fixes a few issues with incorrect extension states and adds
  a cli command, core show device2extenstate, to display all possible
  state mappings.

  (closes issue #15413)
  Reported by: legart
  Patches:
        exten_helper.diff uploaded by dvossel (license 671)
  Tested by: dvossel, legart, amilcar
