81a9580622 all: avoid useless comments and #lines 
Currently we emit useless code for places where we might issue user
content, but there is none.  This commit avoids this.  Besides, some
of the comments looked like implementation details ("Copy the first
part of user declarations"), rather than made for the reader of the
result ("First part of user prologue").

On Bison's parse-gram.c we get:

    @@ -76,10 +76,6 @@
     #define yynerrs         gram_nerrs

5fe636c7ee c++: provide a means to control how location.hh is included 
Users may want to generate the location file elsewhere, say
$top_srcdir/include/ast/location.hh.  Yet, we should not generate
`#include "$top_srcdir/include/ast/location.hh"` but probably
something like `#include <ast/location.hh>`, or `#include
"ast/location.hh", or `#include <location.hh>`.  It entirely depends
on the compiler flags (-I/-isystem) that are used.  Bison cannot guess
what is expected, so let's give the user a means to tell how the
location file should be included.

* data/location.cc (b4_location_file): New.
* data/glr.cc, data/lalr1.cc: Use it.

3e6a075f7f c++: make position.hh completely useless 
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/location.cc: Sort includes.
(b4_position_file, b4_location_file): New.
When there's a file for locations but not for positions, include the
definition of position in the location file.
* data/lalr1.cc (b4_shared_declarations): Include the
position/location file when it exists.
Otherwise, define the class.
* data/glr.cc: Likewise.
* tests/input.at (%define file variables): Check them.

api.position.file and api.location.file.

65e0291619 glr.cc: simplifying the handling of parse/lex params 
The fact that glr.cc uses glr.c makes the handling of parse params

parse function of glr.c.  Yet not all the functions need access to
the parser object.

Work on some other areas of Bison revealed that some macros expanded
to be expanded only once were actually expanded several times.  This

a1d1ab50a0 glr.cc, yacc.c: initialize yylloc properly 
There are several issues to address here.  One is that yylloc should
be initialized when possible.  Another is that the push parser needs
to update yypushed_loc when the user modified it.  And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.

This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable.  To simplify, the local yylloc is not initialized during its
definition.

* data/c.m4 (b4_yyloc_default_define): Replace by...
(b4_yyloc_default): this.
Adjust dependencies.
* data/glr.cc: Initialize yylloc.
* data/yacc.c (b4_declare_scanner_communication_variables):
Initialize yylloc during its definition.
Don't define yyloc_default.
(yypush_parse): The location formal is not const, as we might
initialize it.
(yyparse): Define yyloc_default.
Use it before running the user initial action.
Possibly update the first location on the stack, and the pushed
location after the user initial action.
* tests/actions.at (Initial locations): Check that the initial
location is correct.

dcd5344dcd yacc: remove trailing end of line at end of file 
There are still spurious spaces at the end of some lines.  But this is
addressed in the master branch, and I am reluctant to try to backport
this.

* data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: here.
* tests/calc.at (AT_CHECK_SPACES): New.
Use it.
Be sure not to introduce trailing empty lines in the *.y files.
* NEWS: Doc it.
* cfg.mk (syntax-check): Remove the exception.

d27c5e6534 glr.cc, lalr1.cc: define b4_shared_declarations 
* data/glr.cc, data/lalr1.cc: here.
The name is no longer right, but at least it is consistent with
the other skeletons.

34904c575a glr.cc: no longer require location support

* data/lalr1.cc: M4 quotation changes to highlight code duplication
with glr.cc.
* tests/calc.at: Check glr.cc with and without %location.
While at it, fuse multiple %parse-params into one.
* tests/actions.at: Simplify.
* NEWS: Doc this.
Some other wording changes.
