ESP8266WebServer - Drop inactive connection when another is waiting to improve page load time (#8216)

Browse Source 
* ESP8266WebServer - drop current HC_WAIT_READ connection sooner when another has data

Safari sometimes opens two connections when loading a page and only
sends a request over the second one, resulting in a 5 second wait
(HTTP_MAX_DATA_WAIT) before the request is processed. This commit
drops the current connection after 30ms (HTTP_MAX_DATA_AVAILABLE_WAIT)
when there is a new connection with data available or the buffer of
pending TCP clients is full (currently 5).
