the target name parameter to dns_adb_createfind() was always passed as NULL, so we can safely remove it. relatedly, the 'target' field in the dns_adbname structure was never referenced after being set. the 'expire_target' field was used, but only as a way to check whether an ADB name represents a CNAME or DNAME, and that information can be stored as a single flag.
