afa4ec917b maint: fix bison's own header guards.
Because I'm using a VPATH build with an absolute srcdir, I have
GRAM__USERS_AKIM_SRC_GNU_BISON_SRC_PARSE_GRAM_H.  Before, I was using
a relative srcdir, and had GRAM_______SRC_PARSE_GRAM_H (coming from
../../).  Let it be GRAM_SRC_PARSE_GRAM_H.

* tests/bison.in: Do not depend on the value of $top_srcdir for
Bison itself.
If we were to use relative paths from .c to .y, we would not have
this problem.

3b0b682fd6 fix warnings for useless %printer/%destructor
The previous commit, which turns into a warning what used to be an
error:

    %printer {} foo;
    %%
    exp: '0';

has two shortcomings: the warning is way too long (foo is reported
to be useless later), and besides, it also turns into a warning much
more serious errors:

   %printer {} foo;
   %%
   exp: foo;

Reduce the amount to warnings in the first case, restore the error in
the second.

* src/symtab.h (status): Add a new inital state: undeclared.
* src/symtab.c (symbol_new): Initialize to undeclared.
(symbol_class_set): Simplify the logic of the code that neutralize
the "redeclared" warning after the "redefined" one.
(symbol_check_defined): "undeclared" is also an error.
* src/reader.c (grammar_current_rule_symbol_append): Symbols appearing
in a rule are "needed".
* src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
An unknown symbol appearing in a %printer/%destructor is "used".
* src/reduce.c (nonterminals_reduce): Do not report as "useless" symbols
that are not used (e.g., those that for instance appeared only in a
%printer).
* tests/input.at (Undeclared symbols used for a printer or destructor):
Improve the cover the cases described above.
