* This is a port of Python xml.sax.saxutils quoteattr.

* The function will attempt to choose a quote character in such a way as to
* avoid escaping quotes in the string. If this is not possible the string will
* be wrapped in double quotes and double quotes will be escaped.
*
* @param string $data The string to be escaped
* @param array $entities Associative array of additional entities to be escaped
* @return string Escaped and quoted string
