The PHPAPI php_url_encode_hash_ex() function has had its signature change

[YepYuYu]

 from:
 PHPAPI void php_url_encode_hash_ex(HashTable *ht, smart_str *formstr,
 				const char *num_prefix, size_t num_prefix_len,
 				const char *key_prefix, size_t key_prefix_len,
 				const char *key_suffix, size_t key_suffix_len,
 				zval *type, const char *arg_sep, int enc_type);
 to:
 PHPAPI void php_url_encode_hash_ex(HashTable *ht, smart_str *formstr,
 				const char *num_prefix, size_t num_prefix_len,
 				const zend_string *key_prefix,
 				zval *type, const zend_string *arg_sep, int enc_type);
 The change to use zend_string prevent the computation of the arg_sep
 length at each call. The key_suffix parameter was dropped as it was a
 constant value and depended on the key_prefix parameter to not be NULL.
