Moving most of the task of creating config.h.in from sh to m4.
	Getting rid of acconfig.h by supply a major new family of macros:
	AH_* which make it possible to insert arbitrary text into
	config.h.in.

	* autoheader.m4: Major rewrite: introduction of a set of macros
 	AH_ that produce code into config.h.in.  There are two sets of
 	macros: generic macros, or specialized, documented below.  The
 	basic idea is that an AC_FOO macro which needs an entry in
 	config.h.in should have a sibling AH_FOO which expands into that
 	entry.  In a near future, these macros will be moved next to their
	siblings.

	* autoheader.m4 (AH_VERBATIM, AH_DEFINE, AH_DEFINE, AH_NEED_DECLS,
 	AH_CHECK_SIZEOF, AH_CHECK_FUNCS, AH_CHECK_HEADERS,
 	AH_CHECK_HEADERS, AH_CHECK_LIB, AH_PROG_LEX, AH_FUNC_ALLOCA,
 	AH_C_CHAR_UNSIGNED, AH_AIX, AH_F77_WRAPPERS): New macros.

	* autoheader.m4 (End section): Bind AC_ macros to their
	AH_siblings.

	* autoheader.sh: Remove the sections in charge of SYMS, TYPES,
	FUNCS, HEADERS, LIBS and DECLS: autoheader.m4 is now in charge of
	these.

	* autoheader.sh (options): Added -d, --debug, which does not
	remove the temporary files.

	* autoheader.sh: Instead of redirecting stdout to the output
	stream, always output to a temporary file.  This allows to change
	slightly the consistency check: before autoheader would check that
	each non documented AC_DEFINE is templated in an acconfig.  Now it
	just checks whether the template is in the output file.

	* acconfig.h: Completely emptied, the remaining templates
	(_ALL_SOURCE, __CHAR_UNSIGNED__, F77_FUNC, F77_FUNC_,
 	HAVE_STRINGIZE, and STACK_DIRECTION) are now either associated to
 	their AC_DEFINE, or to one of the new AH_ macros.

	* acgeneral.m4: Reordering of the m4 macros which are not specific
 	to Autoconf.

	* acgeneral.m4 (AC_HAVE_LIB): Promoted from obsolete to hasbeen.

	* acgeneral.m4 (AC_TR_CPP): Fixed quoting problem, and missing ^
	in patsubst.
	(AC_TR_SH): Fixed quoting problem.
