- Update the romcc version.

- Add an additional consistency check to romcc and fix the more obvious problems it has uncovered
  With this update there are no known silent failures in romcc.
- Update the memory initialization code to setup all 3 of the memory sizing registers properly
- In auto.c test our dynamic maximum amount of ram.
