doc: promote yytoken_kind_t, not yytokentype
...
* data/skeletons/c.m4 (yytoken_kind_t): New.
* data/skeletons/c++.m4, data/skeletons/lalr1.cc (yysymbol_kind_type):
New.
* examples/c/lexcalc/parse.y, examples/c/reccalc/parse.y,
* tests/regression.at:
Use them.
* doc/bison.texi: Replace "enum yytokentype" by "yytoken_kind_t".
(api.token.raw): Explain that it forces "yytoken_kind_t" to coincide
with "yysymbol_kind_t".
(Calling Convention): Mention YYEOF.
(Table of Symbols): Add entries for "yytoken_kind_t" and
"yysymbol_kind_t".
(Glossary): Add entries for "Kind", "Token kind" and "Symbol kind".

examples: reccalc: really compile cleanly in C99
...

* examples/c/reccalc/parse.y (yyscan_t): Define it with the same
guards as used by Flex.
