Adela Vais 4bd4cdf377 d: add token constructors support

The user can return from yylex() by calling the Symbol method of the
same name as the TokenKind reported, and adding the parameters for
value and location if necessary.  These methods generate compile-time
errors if the parameters are not correlated.  Token constructors work
with both %union and api.value.type union.

* data/skeletons/d.m4: Here.
* tests/calc.at: Test it.

what the language is (so what compiler tool chain to use, what definition of yylex/yyerror, etc.)
what skeleton is used
