SDL - attempt to fix https://github.com/ValveSoftware/Dota-2/issues/1199 of mouse not locking in Dota. This fix is proposed by Ryan Gordon (increase timeout in X11_SetWindowGrab from 250ms to 5000ms). I'm going to integrate to source2 and ship it to dota customers. If it works, SamL will upsteam it to SDL.
