Simplify callers.

_are_ used.

symbol argument.
This neutralizes a warning in yypush_ when there are no symbols
with a semantic values.
(yy_destroy_): Remove useless "use" of yymsg.

Use quotearg as often as possible instead of leaving the choice of
the quotes to the translators. Use shorter messages. Factor similar

Standard output was never explicitly closed, so we could not
detect failure. Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
rather than standard output.
* bootstrap.conf (gnulib_modules): Add closeout.
* src/main.c: Include "closeout.h".
Use atexit to ensure we close stdout.
* .gitignore: Ignore new files pulled in via gnulib-tool.

Updating to gnulib pulled in new quote and quotarg modules,
by which quoting is now done like 'this' rather than `this'.
That change induces many "make check" test failures. This change
adapts code and tests so that "make check" passes once again.
* src/scan-code.l: Quote like 'this', not like `this'.

Updating to the latest bootstrap from gnulib involves more of a
change than usual, and updating to the latest gnulib would involve
its own set of challenges with the upcoming quoting changes, so
we update bootstrap manually and separately.
* bootstrap: Update from gnulib.
* lib/Makefile.am: Initialize more variables to empty, so that gnulib.mk
can append to them with "+=".
* bootstrap.conf (gnulib_mk_hook): Remove. No longer honored.
(gnulib_tool_option_extras): Generate gnulib.mk.

* cfg.mk (exclude_file_name_regexp--sc_require_config_h_first):
Exempt data/glr.c and data/yacc.c from the include-config.h-first
requirement.
(cherry picked from commit 77f114dd6e)
* cfg.mk (exclude_file_name_regexp--sc_space_tab): Exempt
tests/input.at and tests/c++.at, since they appear to use
SP-TAB sequences deliberately.
* OChangeLog: Remove space-before-TAB.
