XML-RPC Wordpress api setOption double escapes args

[jachzen]

Parts of the xml-rpc wordpress api are not usable, as they doublequote strings. e.g. "Munich's" becomes "Munich
's".

wp.setOptions($args) escpapes all args and calls update_option() which is then calling mysql_real_escape_string(), leading to a double escaping. To solve this options should not be escaped in wp-setOptions() function.

Here the callStack showing the 2nd escaping:
wp-includes/wp-db.php.wpdb->_real_escape:884
wp-includes/wp-db.php.wpdb->escape_by_ref:950
wp-includes/wp-db.php.array_walk:0
wp-includes/wp-db.php.wpdb->prepare:1003
wp-includes/wp-db.php.wpdb->update:1365
wp-includes/option.php.update_option:258
