A networked error on .read() will not make the client disconnected.

Is somebody interested in looking at that?

I've updated the code that uses read() so that it correctly uses these return values:
-1: connection error, isConnected should then return false
0: zero bytes received within the time available, no connection error

0: the number of bytes received, no connection error

This works on Linux, I'm not sure about the Arduino read() implementation following these requirements properly.

I've added a test for disconnection which works on Linux. All that remains is to check it works on Arduino.
