Make QAbstractSocket's API virtual where needed.

The following methods have been made virtual:
setReadBufferSize()
socketDescriptor()
setSocketDescriptor()
socketOption()
setSocketOption()
waitForConnected()
waitForDisconnected()

Now that these methods are virtual we no longer need the nasty
polymorphism workarounds for QSslSocket.
