tipc: introduce publication lists struct
There is currently a single list that is containing both cluster-scope and zone-scope publications, and the list count is a separate free floating variable. Create a struct to bind the count to the list, and to pave the way for factoring out the publications into zone/cluster/node scope. The current "publ_root" most matches what will be the cluster scope list, so it is named accordingly in this commit.
