Dieter Plaetinck d5afe0a577 TSDB: Use a dedicated head chunk reference type (#9501 ) * Use dedicated Ref type Throughout the code base, there are reference types masked as regular integers. Let's use dedicated types. They are equivalent, but clearer semantically. This also makes it trivial to find where they are used, and from uses, find the centralized docs.
