XResetScreenSaver is in typical X11 while new XScreenSaverSuspend needs
Xss extension but it is the desired solution.

XWarpPointer will work always but it is some kind of a hack.
Using Xtst and fake keypress will be a good hack too but need this
particular extension of Xserver. Anyway with some unused keycodes it
could be worth using.

Mplayer should use XScreenSaverSuspend call if Xserver
supports it and additionally Xtst method if it's present and
XWarpPointer as a last resort. Usage of these hacks should be optional
so default proper behaviour will be XScreenSaverSuspend call.
Other hacks are not bound to X11 protocol and are user desktop specific
and not network transparent so should be abandoned.

I must test Xtst solution a  little more so I can make a patch
compliant with presented above logic.
