Add support for an Autotest test suite for Bison.
* m4/m4.m4, m4/atconfig.m4: New files. * m4/Makefile.am (EXTRA_DIST): Adjust. * tests/suite.m4, tests/Makefile.am, tests/atgeneral.m4: New files. * src/getargs.c: Display a more standard --version message. * src/reader.c (reader): Formatting changes. No longer depend upon VERSION_STRING. * configure.in: No longer use `dnl'. Set up the test suite and the new directory `tests/. (VERSION_STRING): Remove.
