* src/counterexample.c, src/derivation.c:
Do not output diagnostics on stdout, that's the job of stderr, and the
testsuite heavily depend on this.
Do not leave trailing spaces in the output.
* tests/counterexample.at: Use AT_KEYWORDS.
Specify the expected outputs.
* tests/local.mk: Add counterexample.at.
With input such as
%token<fl> yVL_CLOCK "/*verilator sc_clock*/"
we generate
yVL_CLOCK = 610, /* "/*verilator sc_clock*/" */
which is invalid since the comment will actually be closed on the
first "*/". Let's turn "*/" into "*\/" to avoid this. But GCC will
also warn about "/*" inside a comment, so let's "escape" it too.

Let's make a difference between places where Perl is required for the
test (AT_PERL_REQUIRE), and the places where it's used to run the
test, but it's not not to run the test (AT_PERL_CHECK).
* tests/local.at (AT_REQUIRE): New.
(AT_PERL_CHECK, AT_PERL_REQUIRE): New.
Use them where appropriate.
* tests/local.mk ($(TESTSUITE)): Beware not to start the line with
'-pi' if Perl is empty, as Make understands this as "it's ok to fail".
Which it is not.
Currently we properly use the "best" integral type for tables,
including those storing state numbers. However the variables for
state numbers used in yyparse (and its dependencies such as
yy_stack_print) still use int16_t invariably. As a consequence, very
large models overflow these variables.
Let's use the "best" type for these variables too. It turns out that
we can still use 16 bits for twice larger automata: stick to unsigned
types.
However using 'unsigned' when 16 bits are not enough is troublesome
and generates tons of warnings about signedness issues. Instead,
let's use 'int'.

Use Automake comments so that we don't get a copy of each in the
generated Makefile.
In C++ pre C++11 it is standard practice to use 0 for the null pointer.
But GCC pre 8 -std=c++98 with -Wzero-as-null-pointer-constant warns about
this.
So disable -Wzero-as-null-pointer-constant when compiling C++ pre 11.
Let's do this in AT_DATA_SOURCE_PROLOGUE (which is pasted on top of
all the test grammar files). Unfortunately, that shifts all the
locations in the expected error messages, which would be too noisy.
Instead, let's introduce testsuite.h, which can vary in length, and
include it in AT_DATA_SOURCE_PROLOGUE.
* tests/testsuite.h: New.
Disable -Wzero-as-null-pointer-constant's warning with GCC pre 8,
C++ pre 11.
* tests/local.at (AT_DATA_SOURCE_PROLOGUE): Use it.
* tests/atlocal.in (CPPFLAGS): Find it.

* tests/local.mk (maintainer-push-check, maintainer-xml-check)
(maintainer-release-check): Rename as...
(maintainer-check-push, maintainer-check-xml)
(maintainer-check-release): these.
* data/lalr1.java: Capture the declarations as m4 macros to avoid
duplication. When push parsing, the declarations occur at the class
instance level rather than within the parse() function.
Change the way that the parser state is initialized. For
push-parsing, the parse state declarations are moved to
"push_parse_initialize()", which is called on the first invocation of
"push_parse()". The %initial-action code is also inserted after the
invocation of "push_parse_initialize()".
The body of the parse loop is modified to return values at appropriate
points when doing push parsing. In order to make push parsing work,
it is necessary to divide YYNEWSTATE into two states: YYNEWSTATE and
YYGETTOKEN. On the first call to push_parse(), the state is
YYNEWSTATE. On all later entries, the state is set to YYGETTOKEN. The
YYNEWSTATE switch arm falls through into YYGETTOKEN. YYGETTOKEN
indicates that a new token is potentially needed. Normally, with a
pull parser, this new token would be obtained by calling "yylex()". In
the push parser, the value YYMORE is returned to the caller. On the
next call to push_parse(), the parser will return to the YYGETTOKEN
state and continue operation.

* tests/local.mk: Prefer passing variable assignment by
the command line, instead of the environment, so that it
is reported in the logs.
Prefer single quotes for shell literal strings.
* tests/local.at: Go for colors.
(--compile-c-with-cxx): New option.
We used to pass "CC=$CXX" as command line argument,
but it was not possible to adjust CFLAGS accordingly
in atlocal, since it is loaded before assignments on
the command line are honored (so that the command line
takes precedence).
* tests/atlocal.in: Implement it.
* tests/local.mk: Use it.
* tests/local.mk (check_SCRIPTS): Add atlocal and atconfig so
that they are properly updated before running tests.
(RUN_TESTSUITE_deps): New.
Use it to factor the dependencies of "*-check" targets,
especially those that don't bounce to the regular
"check-local" target, since then they don't benefit from the
proper dependencies (such as atlocal).
The directory was still using a local Makefile.am because it provides
"scoped" Make variables: these examples are not meant to use the same
CPPFLAGS etc. If we were to use the same -I set, we'd pick up
gnulib's stdio.h for instance, which we do not want for these simple
examples.
Yet, as a result, the dependencies are less accurate, there is code
duplication, etc. This is especially perceptible when trying to
extract more examples from the documentation, as will be done in
forthcoming changes.
In order to make the tuning of CPPFLAGS easier, discard the predefined
-I from Automake.
* examples/calc++/Makefile.am: Rename as...
* examples/calc++/local.mk: this.
Adjust the paths which are now rooted in top_srcdir/top_builddir.
Handle BISON_CXX_WORKS here, instead of the too crude previous
approach that completely discarded the whole directory.
($(BISON)): Remove now useless bouncing recipe.
(calc___CPPFLAGS): New.
Stay away from -Ilib.
* Makefile.am, configure.ac, examples/local.mk,
* examples/calc++/test: Adjust.

Make testsuite.at its first argument.

This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
* tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
Solves problems when top_srcdir is an absolute path.
Suggested by Eric Blake.
* configure.ac: Require Autoconf 2.62.
* tests/local.mk (tests/atconfig): The rule was incorrect, but
remove it: now that there is no tests/Makefile.am, the top-level
Makefile properly updates atconfig when needed.
