WindowServer: Normalize preferred rect before applying

Browse source 
Previously, SetWindowRect and SetWindowRect could supply basically arbitrary
x and y coordinates. This could happen either due to a malicious or malfunctioning
program, or even due to the auto-centering feature.

This patch also moves the 'normalization' code out of ClientConnection to Window,
where it belongs better.

Fixes #4135.
Fixes #5052.
