Minor preparatory refactoring for UPDATE row movement.

Generalize is_partition_attr to has_partition_attrs and make it
accessible from outside tablecmds.c.  Change map_partition_varattnos
to clarify that it can be used for mapping between any two relations
in a partitioning hierarchy, not just parent -> child.

Some comment changes by me.
