<p>This function is used to parse an URI. If no scheme defaults
are provided, the value of
<seealso marker="#scheme_defaults">scheme_defaults</seealso>
function will be used. </p>
<p>Note that when parsing an URI with an unknown scheme (that is,
a scheme not found in the scheme defaults) a port number must be
provided or else the parsing will fail. </p>
<p>If the fragment option is true, the URI fragment will be returned as
part of the parsing result, otherwise it is completely ignored.</p>
