TOR space reductions

These changes avoid some waste of valuable memory used to store
TOR and rings contained in TOR. This is mostly needed as a SEEPROM relief.

Contains:
- 12 byte ring header (former 31551 commit)
- less zero padding at the end of compressed ring (former 31524 commit)
- removed an additional ring meta data structure (former 31524 commit)

In addition, it contains these fixes:
- fixed a bunch of scan addresses (former 33969 commit)
- increased size of ring decompression buffer (former 32796 commit)
- zero byte ring padding up to 4 byte boundaries for SBE (former 33969
  commit)
- added dbgl control of error trace after call to get_ring_from_sbe_image
- added enumerated ringId to the RS4v3 header
- fixed incorrect scan address masks for even/odd EX RS4 v3 ring handling
  in MVPD accessor functions
- fixed incorrect scan address region bits for odd EX rings translated from
  RS4 v2 to RS4 v3 in MVPD accessor functions
