Add "lexparse.h" headers for lexer/parser integration (#112)

And include them in a few strategic places.  This avoids build
failures with future compilers that do not support implicit function
declarations by default.

(NB: This commit does not regenerate the lexers/parsers, so the
line numbers are slightly off.)
