46bdb8ec59 errors: don't display "warnings treated as errors"
This line doesn't add any meaningful information anymore, the appended
[-Werror=CATEGORY] is enough.  It is actually more insightful, as it
allows to distinguish warnings treated as errors from those that
aren't.  This line is also removed by gcc 4.8.

* src/complain.c (set_warnings_issued): The only action left was
checking if the error bit corresponding to the warning issued was set,
and that function was only called once. Therefore, remove it, and do
its job directly in the caller...
(complains): here.
* src/complains.h: Adjust.
* tests/input.at: Adjust.
* NEWS: Document this change.

1048a1c901 errors: change output, and improve -y coherence
The prefix of warnings treated as errors is now "error: ". Also, their
suffix now reflects the changes in the Werror option format.

An output for -Werror=other used to be:
  bison: warnings being treated as errors
  input.y:1.1: warning: stray ',' treated as white space [-Wother]

It is now:
  bison: warnings being treated as errors
  input.y:1.1: error: stray ',' treated as white space [-Werror=other]

The line "warnings being treated as errors" no longer adds any info,
it will be removed in a forthcoming change.

* NEWS: Add entry "Enhancement of the -Werror"
* doc/bison.texi: Move the warnings-as-error to a new bullet.
* src/complain.c (complains): Refactor, change the prefix of warnings
that are treated as errors.
(warnings_print_categories): Support for [-Werror=CATEGORY] display
* src/getargc.c (getargs): -y implies -Werror=yacc
* tests/input.at: Update expected --yacc output for coherence.

24d96dd3eb errors: indent "result type clash" error context
This used to be the format of the error report:

  input.y:6.5-10: result type clash on merge function 'merge': [...]
  input.y:2.4-9: previous declaration

In order to distinguish the actual error from the context provided, we
rather this new output:

  input.y:6.5-10: result type clash on merge function 'merge': [...]
  input.y:2.4-9:     previous declaration

Another patch will introduce an "error: " prefix to all non-indented
lines, giving yet better readability to the reports.

d87ea54cf6 warnings: use the regular interface for s/r and r/r conflicts
The current routines used to display s/r and r/r conflicts are both
inconvenient from the programmer point of view (they do not use the
warning infrastructure) and for the user (the messages are rather
terse, not necessarily pleasant to read, and because they don't use
the same routines, they look different).

It was due to the belief (dating back to the initial checked-in
version of Bison) that, at some point, POSIX Yacc mandated the format
for these messages.  Today, the Open Group's manual page for Yacc,
<http://pubs.opengroup.org/onlinepubs/009695399/utilities/yacc.html>,
explicitly states that the format of these messages is unspecified.
See commit be7280480c and
<http://lists.gnu.org/archive/html/bison-patches/2002-12/msg00027.html>.

For a discussion on the chosen warning format, see
http://lists.gnu.org/archive/html/bison-patches/2012-09/msg00039.html

In an effort to factor the handling of errors and warnings, use the
Bison warning routines to report these messages.
