output: use the token list to define the yytokentype

There are currently two systems used to pass information about tokens to
m4: the original one, and another, which is used for instance for
printers and destructors, variants etc.  Move to using only the latter.

* data/bison.m4 (b4_symbol_map, b4_token_visible_if)
(b4_token_has_definition, b4_any_token_visible_if, b4_token_format): New.
* data/c++.m4, data/c.m4, data/glr.c, data/java.m4: Adjust to use them.
