Also adds a new member to afr_local_t, local->first_up_child which is initialized at the start of the transaction.

(for writes, both stub and request are destroyed when refcount becomes 0, which happens only when the write operation is stack unwound and a reply for the write operation has come from underlying translators, for non-write unwind requests the request is first destroyed before resuming the stub).
