c++: use YYRHSLOC.

Browse Source 
* data/lalr1.cc (YYRHSLOC): New.
	(YYLLOC_DEFAULT): Use it.
	* data/glr.cc: If location_type was user defined, do not include
	location.hh, and do not produce location.hh and position.hh.
	* tests/calc.at (YYLLOC_DEFAULT): Use YYRHSLOC.
	Check that glr.cc supports user defined location_type.
	* NEWS: Document this.
