isValid
Parses @uri_string according to @flags, to determine whether it is a valid relative-absolute-uris, i.e. it does not need to be resolved relative to another URI using g_uri_parse_relative().
If it’s not a valid URI, an error is returned explaining how it’s invalid.
See g_uri_split(), and the definition of #GUriFlags, for more information on the effect of @flags.
Return
true if @uri_string is a valid absolute URI, false on error.
