Akim Demaille f0f95a50ee c: no longer require stdio.h when locations are enabled ...

Recent changes (in 2.7) introduced a dependency on both FILE and
fprintf, which are "available" only in %debug mode.  This was to
define yy_location_print_, which is used only in %debug mode by the
parser, but massively used by the test suite to output the locations
in yyerror.

Break this dependency: the test suite should define its own routines
to display the locations.  Eventually Bison will provide the user with
a means to display locations, but not yet.

* data/c.m4 (b4_yy_location_print_define): Use YYFPRINTF instead of
fprintf directly.
* data/yacc.c (b4_yy_location_print_define): Invoke it only in %debug
mode, so that stdio.h is included (needed for FILE*), and YYFPRINTF
is defined.

* tests/local.at (AT_YYERROR_DECLARE, AT_YYERROR_DEFINE): Declare
and define location_print and LOCATION_PRINT.

* tests/actions.at, tests/existing.at, tests/glr-regression.at,
* tests/input.at, tests/named-refs.at, tests/regression.at: Adjust
to use them.
Fix the expected line numbers (as the prologue's length has changed).
