hw/xquartz: Various fixes for pseudoramiX.c

Browse source 
Various fixes, applied to panoramiX.c in commit 2b266eda, also need applying to pseudoramiX.c:
 Fix panoramiX request and reply swapping
 Set window and screen values in panoramix replies
 Prevent buffer overrun in ProcPanoramiXGetScreenSize

These fixes seem to be necessary in order to compile pseudoramiX.c with gcc
