stdbool: do not define HAVE_STDBOOL_H
* m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Renamed from
AC_HEADER_STDBOOL. All uses changed. Do not define
HAVE_STDBOOL_H, as gnulib does not need this. This change is
imported from the latest Autoconf git. It was motivated by Emacs,
which uses gnulib but does not need HAVE_STDBOOL_H.
