The extra persistant state that we're recording per channel should really
be stored in the channel struct in innd.  I would add an additional
variable to the channel struct; I think it will be visible in all the
places that you need it.

In practice, this doesn't really matter that much at present since innd
uses static variables in rather too many places, but in the long run it
would be nice to get rid of them wherever possible.  (That will be needed
if we were ever to make innd threaded, for instance.)
