Log message:
Added FUSION_REF_WATCH which can be used to install a reference watcher with
an optional argument that will be passed to it.

The reference watcher is a call that is executed when the reference counter
gets zero. The optional argument could, for example, be the id of a user space
resource associated with that reference.

This is a much better way than polling all references regularly.
