* WiFiServer - 'rename' available() to accept()
* use server.accept() instead of available()
* WiFiServer.accept() and ArduinoWiFiServer class doc update
* 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).
Fixes#5116Fixes#2743
The Arduino WiFiClient object allows sending the same packet to all
connected clients of a WiFiServer. In their implementation it may make
sense, but on the 8266 with things like SSL it doesn't.
Update the docs to note that WiFiServer::write() is a no-op, and that
the app should use the WiFiCliebnt::write() on all connected clients as
appropriate.
