Use %pure-parser in grammar files to make Bison 3 happy.

Use %pure-parser in grammar files to make Bison 3 happy.

This avoids a "deprecated directive, use ‘%pure-parser’ [-Wdeprecated]"
warning in css/CSSGrammar.y and xml/XPathGrammar.y when building with
Bison 3.

So long as it still works in bison 2, or whatever most folks use.  Also, please
remove the BUG= line if it's empty.

https://code.google.com/p/lilypond/issues/detail?id=3488 has some condensed
info, the gist is that the dash variant still works in bison 2, the underscore
might stop working in bison 3 at some point. There's also an even newer "%define
api.pure" but it is not that compatible (and I'm not pushing for it).
