Always suspicious that some un-expected dialog / state can cause
strange behavior in a client. An initial cut at an API to make it
easier to unwind such problems by exposing the toolkit state.

If a document is opened in several Online views, each of them using
a different zoom, then the scale cache is used for the scaling,
and each view is sent updated tiles, so if there are too many
views, the cache is not large enough.

There was a problem in the iOS app where a callback was done passing a
registered mpPollClosure that pointed to the mainKit variable in
lokit_main() even though that variable had already gone out of scope
and been destructed.

Introduce unregisterPollCallbacks(), which just sets the mpPollClosure
pointer to null. That means no callbacks should be done any more. It
does not mean that Unipoll would not be active. Change isUnipoll() to
look at whether the mpPollCallback pointer has been set or not.
