Code bootstrap

Now that default abort works it's time to start adding some primitives
and a bootstrap reader (sexp -> C).

Seems straightforward once list -> code translation works.  (eval).

Before going there, I think it's best to do the shared primitives
anyway.  The PF core can benefit greatly from _expressions_ : in fact,
almost all code in pf.c is doubly done: once as expression, and once
bound to the linear stack.
