TOR reduction: Ditching DeltaRingLayout and RingLayout_t

- Complete overhaul of get_ring_from_sbe_image for improved clarity
  in effort to remove anything related to 8Byte RingLayout header,
  incl built-in and hardcoded assumptions.
- Functional overhaul of get_ring_from_cme/sgpe_image, but only
  slight improvement in clarity. Also removed any traces of
  RingLayout assumptions. (Beautification of these functions
  will be in separate commit.)
- Overhaul of tor_append_ring for clarity and improved clarity
  elsewhere where PUT_SINGLE_RING is used.
- Updated p9_tor.C|H in order to expose version 2 of TOR API,
  which eliminates the 8B RingLayout structure, in order to
  work with Cronus which currently assumes, due to pulling in
  the p9_tor.H header file, that RingLayout structure is being
  used.
- Updated p9_scan_compression.C to remove most zero padding at end
  of compressed ring (i.e., merged commit 32647 into this commit
  in order to be able to merge into gerrit).
  - The scan compression code used to pad the compressed ring at its
    end with zeros up to the next 8 byte boundary. For P9, no
    padding is needed. Most of this padding is now removed, just
    keeping a padding to the next 2 byte boundary for convenience.
    Removal of these padding bytes saves about 400 bytes in SEEPROM.
- Added p9_ipl_build.C because it assumes an 8B alignment of the
  SBE ring block which is no longer the case with RS4v3. We've
  been lucky so far in our tests.
