Some LOK messages may get called very often, such as updates about
cursor position. And since only the last one matters, they get
generated every time, which costs some time, and then later except
for one they get all discard again from CallbackFlushHandler queue,
which again costs time.
Change the model to instead only set an 'updated' flag, and
CallbackFlushHandler will request the actual message payload only
before flushing.
This commit changes LOK_CALLBACK_INVALIDATE_VISIBLE_CURSOR and
LOK_CALLBACK_INVALIDATE_VIEW_CURSOR to work this way.
