[Freeciv-Dev] (PR#17741) Client does not handle input with timeout -1

Hello!

When timeout is set to -1, the game no longer handles input from 
keyboard or mouse, and is effectively frozen. The same problem occurs 
when time timeout is set too low, so the phase where units are moved 
around between turns takes longer than the timeout. I think that I have 
also seen this when my players gets killed, and there is only AI players 
remaining. The only solution to this is to kill the client and server.

The game should be forgiving towards user-settings, and allow them to be 
undone. Prioritize handling user-input over everything else. I started 
making a patch, handling outstanding GTK events in gui_flush(), but it 
reduced performance and framerates, so I have no suggested solution 
right now.

Reproducible with the Gtk+2 client in 2.0, 2.1 and the latest SVN version.
