errors: change output, and improve -y coherence

Browse Source 
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.

* Short term
** erroneous test
src/complains.c changed the output of errors (prefixes), but the m4 macros
have not been changed to reflect this change.
Fix the message "an identifier expected" (m4) in tests/input.at.
** push-parser
Check it too when checking the different kinds of parsers. And be
sure to check that the initial-action is performed once per parsing.
