c++: make position.hh completely useless

Browse Source 
Let's put the definition of position into location.hh, there's no real
value in keeping them separate: they are small, and share the same
requirements.

To help users transition to this new model, still generate position.hh
by default, but as a simple include to location.hh.

* data/location.cc (api.position.file): Accept only 'none' as possible
value.
(position.hh): Make it a stub.
(location.hh): Adjust.
(b4_position_define): Merge into...
(b4_location_define): this.
* data/glr.cc, data/lalr1.cc, tests/input.at, tests/output.at: Adjust.
