36632 - nsIClipboard::HasDataMatchingFlavors() gets called too many times

nsIClipboard::HasDataMatchingFlavors() gets called too many times from editor. 
When I begin typeing in a text field or in composer, it will call it numerous
times.  I could see it asking once, but it gets called quite a few times.  It
would be nice to reduce the number of calls to this function.

reassign to sfraser for initial triage; setting to M16 and perf keyword (though 
it may be pushed off to M17)

This is command enableing happening, I think. We need to be smarter about when we 
update cmd_paste.

I disagree that HasDataMatchingFlavors() is being called too often. When clicking 
in a text widget, it gets called once in response to the focus change, and once 
when you start typing. It is not called continually when typing.

Back to you, pav.
