In a following commit, we will need to add all the oids from a set into
another set. In "list-objects-filter.c", there is already a static
function called add_all() to do that.
Let's rename this function oidset_insert_from_set() and move it into
oidset.{c,h} to make it generally available.
While at it, let's remove a useless `!= NULL`.
