-------------------------+-----------------------------
 By allowing an array of sanitize callbacks when registering a route, we
 can easily add support for multiple sanitize functions.  For example,
 registering with the following callbacks would allow a color to be trimmed
 and then sanitized.

 {{{
 'sanitize_callback' => array(
         'normalize_whitespace',
         'sanitize_hex_color_no_hash',
         ),
 }}}

 Example: http://src.wordpress-develop.dev/wp-
 json/test/multisanitize?color=%20ff0000

 Another example may be someone parsing post IDs from a list, then
 sanitizing it down to valid post IDs with a custom function.

 {{{
 'sanitize_callback' => array(
         'wp_parse_id_list',
         'sanitize_post_ids',
         ),
 }}}

 The attached patch adds support for multiple sanitize_callback handlers.
 The same logic could be applied to validate_callback handlers.
