b6b397b7f0 fixits: report duplicate %yacc directives 
We should use -ffixit and --update to clean files with duplicate
directives.  And we should complain only once about duplicate obsolete
directives: keep only the "duplicate" warning.  Let's start with %yacc.

For instance on:

    %fixed-output_files
    %fixed-output-files
    %yacc
    %%
    exp:

This run of bison:

    $ bison /tmp/foo.y -u
    foo.y:1.1-19: warning: deprecated directive, use '%fixed-output-files' [-Wdeprecated]
     %fixed-output_files
     ^~~~~~~~~~~~~~~~~~~
    foo.y:2.1-19: warning: duplicate directive [-Wother]
     %fixed-output-files
     ^~~~~~~~~~~~~~~~~~~
    foo.y:1.1-19: previous declaration
     %fixed-output_files
     ^~~~~~~~~~~~~~~~~~~
    foo.y:3.1-5: warning: duplicate directive [-Wother]
     %yacc
     ^~~~~
    foo.y:1.1-19: previous declaration
     %fixed-output_files
     ^~~~~~~~~~~~~~~~~~~
    bison: file 'foo.y' was updated (backup: 'foo.y~')

gives:

    %fixed-output-files
    %%
    exp:

* src/location.h, src/location.c (location_empty): New.
* src/complain.h, src/complain.c (duplicate_directive): New.

* src/getargs.h, src/getargs.c (yacc_flag): Instead of a Boolean, be
the location of the definition.
Update dependencies.

* src/scan-gram.l (%yacc, %fixed-output-files): Move the handling of
its warnings to...
* src/parse-gram.y (do_yacc): This new function.

* tests/input.at (Deprecated Directives): Adjust expectations.

ba469451d8 diagnostics: improve the accuracy for %error-verbose 
Avoid duplicate warnings about %error-verbose, once for deprecation,
another for duplicate.  Keep only the duplicate warning for the second
occurrence of %error-verbose.

This will help removal fixits.

* src/scan-gram.l (%error-verbose): Return as a PERCENT_ERROR_VERBOSE
token.
* src/parse-gram.y (do_error_verbose): New.
Use it.
* src/muscle-tab.c (muscle_percent_variable_update): Handle pseudo
variables such as %error-verbose.

72c488aa62 diagnostics: improve them for %name-prefix 
Currently the diagnostics for %name-prefix are not precise enough.  In
particular, they does not show that braces must be used instead of
quotes.

Before:

    foo.y:3.1-14: warning: deprecated directive, use '%define api.prefix' [-Wdeprecated]
     %name-prefix = "foo"
     ^^^^^^^^^^^^^^

After:

    foo.y:3.1-20: warning: deprecated directive, use '%define api.prefix {foo}' [-Wdeprecated]
     %name-prefix = "foo"
     ^^^^^^^^^^^^^^^^^^^^

To do this we need the value passed to %name-prefix, so move the
warning from the scanner to the parser.

Accuracy will be very important for the forthcoming changes.

* src/parse-gram.y (do_name_prefix): New.
(PERCENT_NAME_PREFIX): Have a semantic value: the raw source, with
possibly underscores, equal sign, and spaces.  This is used to provide
a more accurate message.  It does not take comments into account,
but...
* src/scan-gram.l (%name-prefix): Delegate the warnings to the parser.

* tests/headers.at, tests/input.at: Adjust expectations.

aadf6c0bf3 parser: reprecate %nterm back 
After having spent quite some time on cleaning the handling of symbol
declarations in the grammar files, I believe we should keep it.

It looks like it's a duplicate of %type, but it is not.  While POSIX
Yacc requires %type to apply only to nonterminal symbols, it appears
that both byacc and bison accept it for tokens too.  And some
experienced users do actually expect this feature to group
symbols (terminal or not) by type ("On the other hand, it is generally
more useful IMHO to group terminals and non-terminals with the same
type tag together",
http://lists.gnu.org/archive/html/bug-bison/2018-10/msg00000.html).
Even Bison's own parser does this today (see CHAR).

Basically reverts 7928c3e6fb.

* src/scan-gram.l (%nterm): Dedeprecate, but issue a Wyacc warning.
* tests/input.at: Adjust expectations.
(Yacc warnings  on symbols): New.

985d7177e8 parser: no longer use the "braceless" non-terminal 
The purpose of this symbol was only to factor function calls.  As a
result the actions were indeed simpler, but the grammar was somewhat
uselessly obfuscated.  Get rid of this symbol, but introduce functions
to simplify dependencies.

There is no (intended) changes of behavior here.

* src/parse-gram.y (strip_braces, translate_code(

(braceless): Remove, use "{...}" instead, and one of the previous
functions depending on the context.
(STRING, "%{...%}", EPILOGUE): Declare as <code>, instead of <chars>,
the difference between both is useless (well, I couldn't make sense of
it, even after having read the initial commit that introduced them).

        float floatVal;

      } value;

      struct ListElementType* next;
    } ListElementType;
  }

  %union
  {
    ListElementType* list;
  }

  %token <list->value.charptrVal> STRING
  %token <list->value.intVal> INTEGER

bb8e56ff67 warnings: fusion of complain and complain_at 
These functions are very similar, and keeping them seperate makes
future improvements difficult, so merge them.

This impacts 89 calls.

* src/bootstrap.conf: Adjust.
* src/complain.c (complain, complain_at): Merge into...
(complain): this.
(complain_args): Adjust.
* src/complain.h, src/conflicts.c, src/files.c, src/getargs.c,
* src/gram.c, src/location.c, src/muscle-tab.c, src/parse-gram.y,
* src/reader.c, src/reduce.c, src/scan-code.l, src/scan-gram.l,
* src/scan-skel.l, src/symlist.c, src/symtab.c:
Adjust.
