Add support for Bison 3.0.

Browse source 
We still want to remain compatible with Bison 2.7 so instead of fixing
all the new errors reported by 3.0 we silence some warning.  We should
fix these for good once Bison 3.0 is more widespread.

* m4/bison.m4: New file. Test if bison support -Wno-empty-rule and
-Wno-deprecated.  Define BISON and BISON_EXTRA_FLAGS.
* configure.ac: Do not test for yacc, use the above test instead.
* src/dstarparse/Makefile.am, src/eltlparse/Makefile.am,
src/kripkeparse/Makefile.am, src/ltlparse/Makefile.am,
src/neverparse/Makefile.am, src/tgbaparse/Makefile.am: Use BISON
and BISON_EXTRA_FLAGS.
* src/ltlparse/ltlparse.yy: Fix or and remove useless %right/%nonassoc
settings.
* src/eltlparse/eltlparse.yy: Likewise, and remove "%pure-parser".
