patch 7.4.1719

Problem:    Leaking memory when there is a cycle involving a job and a
            partial.

            by them.  Go through all jobs and channels to find unreferenced
            items.  Also, decrement reference counts when garbage collecting.

patch 7.4.1718

Problem:    Coverity: not using return value of set_ref_in_item().
Solution:   Use the return value.
