Mike Kaganski 99c1bd1a4e Disallow closing document during generation of preview
Using an external (Java) script that opens a document, and then quickly
closes it, it may happen that the idle that generates a preview is still
active, when the control thread calls XCloseable::close, which destroys
still used document. This leads to use-after-free.

This uses the close listener in SfxObjectShell, to veto closing document
that is still in use by the preview generation code. After completion,
when the caller of close() transferred ownership, then the call to close
is repeated.
