Frediano Ziglio 1b15983415 Make QXLMessage handling safe 
The QXLMessage has no size so potentially a guest could give an
address that cause the string to overflow out of the video memory.
The current solution is to parse the message, release the resources
associated without printing the message from the client.
This also considering that the QXLMessage usage was deprecated
a while ago (I don't know exactly when).
This patches limit the string to 100000 characters (guest can feed
so much logs in other way) and limit to video memory.
