* acinclude.m4: Move EVO_CHECK_LIB into here, and also create
	EVO_PURIFY_SUPPORT, EVO_TIMEZONE_CHECK, and EVO_LDAP_CHECK from
	stuff in configure.in. (This stuff is also used by Connector.)

	* configure.in: Remove the stuff that was moved to acinclude.m4.

	* evolution_addressbookConf.sh.in: Remove db3 and ldap references
	since pas-backend-file and pas-backend-ldap are no longer in
	libpas, and those flags weren't doing anything useful here before
	anyway. (Our attempts to force static linking to those libraries
	end up getting mangled when passed through gnome-config.)

	* evolution_calendarConf.sh.in: Likewise, remove db3 references.
