[committed] convert intl to autoconf 2.57

[neroden at twcny dot rr dot com (Nathanael Nerode)]

Tested on i686-pc-linux-gnu, plus various hand checks that behavior
hasn't meaningfully changed.  Committed.

	* configure.in: Convert to autoconf 2.57, gratuitous stylistic
	cleanup, rename to configure.ac.
	* configure.ac: Renamed from configure.in.
	* config.h.in: Rebuilt with autoheader 2.57.
	* configure: Rebuilt with autoconf 2.57
	* README: Update to reflect rename of configure.in to configure.ac.
