Akim Demaille f859462658 d: add support for %printer

Currently we display the addresses of the semantic values.  Instead,
print the values.

Add support for YY_USE across languages.

* data/skeletons/c.m4, data/skeletons/d.m4 (b4_use): New.
* data/skeletons/bison.m4 (b4_symbol_actions): Use b4_use to be
portable to D.

Add support for %printer, and use it.

* data/skeletons/d.m4: Instead of duplicating what's already in
c-like.m4, include it.
(b4_symbol_action): New.
Differs from the one in bison.m4 in that it uses yyval/yyloc instead
of *yyvaluep and *yylocationp.

* data/skeletons/lalr1.d (yy_symbol_print): Avoid calls to formatting,
just call write directly.
Use the %printer.
* examples/d/calc/calc.y: Specify a printer.
Enable traces when $YYDEBUG is set.
* tests/calc.at: Fix the use of %printer with D.

README.md

This directory contains examples of Bison grammar files, sorted per language.

Several of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.

These examples come with a README and a Makefile. Not only can they be used to toy with Bison, they can also be starting points for your own grammars.

Please, be sure to read the C examples before looking at the other languages, as these examples are simpler.
