[svn-r5132] Purpose:

	Autotools Update
Description:
	I've updated autoconf, automake, and libtool to the latest/greatest
	versions; 2.53, 1.6, and 1.4.2 resp.

	Many changes come with the new versions:

		- ltconfig is no longer used
		- acconfig.h is no longer used (#define values are declared with
		  the macro)
		- regeneration of all of the aclocal.m4, configure, and
		  H5config.h.in files.
		- new config.{guess,sub} files
		- new ltmain.sh file
Platforms tested:
	AIX (blue), and Linux
