@brief Prefetch the maximum request length without blocking.
@param c: The connection to the X server.
Without blocking, does as much work as possible toward computing
the maximum request length accepted by the X server.
Invoking this function may cause a call to xcb_big_requests_enable,
but will not block waiting for the reply.
xcb_get_maximum_request_length will return the prefetched data
after possibly blocking while the reply is retrieved.
Note that in order for this function to be fully non-blocking, the
application must previously have called
xcb_prefetch_extension_data(c, &xcb_big_requests_id) and the reply
must have already arrived.
