- moved util_link_responding_p and util_get_http_status to http-client-procs and based it on util::http::*. - marked util_link_responding_p and util_get_http_status as deprecated, moved a new version into the util::* namespace and turned positional arguments into non-positional
- add new utility-function for en/decoding the "path" part using the url-encding scheme as define in RFC 3986. The functions are defined as stubs for backward compatibility for aolserver, since aolserver uses always the same encoding - use ad_urlencode_path in file-storage where necessary - some cleanup
