/**
* Parse functional URI notation, as per 4.3.4 of CSS 2.1
*
* http://www.w3.org/TR/CSS21/syndata.html#uri
*
* > The format of a URI value is 'url(' followed by optional white space
* > followed by an optional single quote (') or double quote (") character
* > followed by the URI itself, followed by an optional single quote (')
* > or double quote (") character followed by optional white space
* > followed by ')'. The two quote characters must be the same.
*
* Example:
* \verbatim
url = extract_uri("url('foo')bar", &out);
-> url == "foo"
-> out == "bar"
\endverbatim
*
* @param s String which starts with "url("
* @param[out] endptr points to \c s + N, where N is the number of characters parsed
* @return URL string, or empty string on failure
