smart handling of NotifyUngrab crossing events

closing a keyboard driven popup had the sideeffect to return the focus
where the pointer is, regardless of whether that window had the focus
before (due to a NotifyUngrab crossing event), bug #597
This was resolved by simply ignoring NotifyUngrab mode crossings, but
that had the unfortunate sideeffects to break focus passing when the
mouse was actually moved (in a DnD operation, 730) or the focus shall be
passed on for strict mouse focus and a mouse triggered lower action (1012)

So instead we record the window that was last entered by a *real*
crossing and only ignore the NotifyUngrab event if this window didn't
change.

BUG: 1012
