	* README: Included information about db3.

	* acconfig.h: Added HAVE_DB_H and HAVE_DB3_DB_H.

	* configure.in: Added various checks for db3 libraries and
	includes.  Of note are the new configure options
	--with-db3-includes=PREFIX and --with-db3-libs=PREFIX to specify
	the location for your db3 library.
