New API: gst_uri_from_string_escaped() Identical to gst_uri_from_string() except that the userinfo and fragment components of the URI will not be unescaped while parsing. This is needed for correctly parsing usernames or passwords with `:` in them such as reported at: https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/831 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/583>
