RFC/RFA: basic-improvements: split config.h and tm.h

I think this is a pretty good plan.

I don't understand this step:

  Step three is a mechanical change that touches every last .c file,
  inserting #includes of coretypes.h and tm.h after system.h.  Unlike
  the last time, I am not going to try to winnow it down any at this
  stage.  The Makefiles change to match, and the inclusions are removed
  from config.h and hconfig.h.

What about tconfig.h?  If a file includes tconfig.h, and then it also
includes coretypes.h, won't we have trouble?
