Roadmap: constant dependencies

1. Remove pic18-const

2. Make an interface for the minimally needed constants used in the
   compiler and possibly library code.

3. Make it so that there is no longer a top pic18.ss interface, but a
   unit that still requires linkage with a chip-specific module.

4. Turn everything into a unit, and splice off the parser.
   -> Make this work for macros.

wow.. does this open a can of worms or what!
