* cpplib.h: Provide HASHNODE typedef and forward decl of struct hashnode only. Kill cpp_hashnode typedef. MACRODEF, DEFINITION, struct hashnode, struct macrodef, struct definition, scan_decls prototype, default defn of INCLUDE_LEN_FUDGE moved elsewhere. * cpphash.h: MACRODEF, DEFINITION, struct macrodef, struct definition, and struct hashnode moved here. Remove the unused 'predefined' field from struct definition. Replace the 'args' union with its sole member. All users updated (cpphash.c). Delete HASHSTEP and MAKE_POS macros, and hashf prototype. Add multiple include guard. * cpphash.c (hashf): Make static; use better algorithm; drop HASHSIZE parameter; return an unsigned int. (cpp_lookup): Drop HASH parameter. PFILE parameter is used. Calculate HASHSIZE modulus here. (cpp_install): Drop HASH parameter. Calculate HASHSIZE modulus here. (create_definition): Drop PREDEFINITION parameter. * cpplib.c (do_define): Don't calculate a hash value here. Don't pass (keyword == NULL) to create_definition. * scan.h: Prototype scan_decls here. * cppfiles.c: Move INCLUDE_LEN_FUDGE default defn here. * cppexp.c, cppfiles.c, cppinit.c, cpplib.c, fix-header.c: All callers of cpp_lookup and cpp_install updated.
