Centaur ring support - TOR API

Key_Cronus_Test=XIP_REGRESS

- Updates to TOR API codes to allow user codes to call TOR API
  function on a Centaur image. Note that the API no longer needs
  the caller to supply and XIP section ID.
- Updates to TOR API codes to take advantage of the improved
  data and meta-data representation in the ring Id codes and
  the more self-contained ring image which now has the TOR magic
  header.
- Updates to xip_tool to allow dissection of Centaur image.
- Additional updates to TOR API codes and ring Id codes to continue
  improving overall clarity of data, data structures and flow
  through TOR API, incl name changes to related data variables
  and structures.
