Subject: [PATCH] Rename build/*.ac to build/configure.ac.*.

Also rename configure.in to configure.ac (finally)

	configure.in		-> configure.ac
	build/analysis.ac	-> build/configure.ac.analysis
	build/enable.ac		-> build/configure.ac.enable
	build/system.ac		-> build/configure.ac.system
	build/tools.ac		-> build/configure.ac.tools
	build/version.ac	-> build/configure.ac.version
	build/warnings.ac	-> build/configure.ac.warnings
