Jeremy Huddleston 0f613007cd CheckWindowOptionalNeed: Ensure w->optional is set to avoid SEGFAULT
If CheckWindowOptionalNeed is called consecutively (and the first removes optional), then
we will SEGFAULT.  This can happen in XQuartz because ReparentWindow will call
pScreen->ReparentWindow which can DeleteProperty which will CheckWindowOptionalNeed... then
ReparentWindow will call it again later indiscriminantly.
