@brief Prefetch of extension data into the extension cache
@param c: The connection.
@param ext: The extension data.
This function allows a "prefetch" of extension data into the
extension cache. Invoking the function may cause a call to
xcb_query_extension, but will not block waiting for the
reply. xcb_get_extension_data will return the prefetched data after
possibly blocking while it is retrieved.
