+/**
+ * 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
