This is a simple recursive-descent parser which understands a subset of
the C type grammar.
Rule functions are suffixed _seq if they scan a sequence of items;
_opt if they may consume zero tokens; _seqopt if both are true. The
"consume_" prefix indicates that a sequence of tokens is parsed for
syntactic correctness and then thrown away.
Simple one-token lookahead mechanism.
