There isn't any need to create an actor per call to the parent. This patch lines up PaymentRequest with PPaymentRequestChild objects and links them together. It also simplifies the maps and arrays we use to keep track of these objects. There's one tricky bit to note in this patch: in the case that a promise is passed to paymentRequest.show(), we don't notify the parent process until the promise resolves (when we call either UpdatePayment or AbortUpdate). In that case, I needed to distinguish between an "update" because of the promise resolving or a call to updateWith on an shippingaddresschange event in order to get the bookkeeping right with the mActivePayments hashtable. In that case, the PaymentRequest is kept alive by mShowingRequest alone. In all other cases, mActivePayments keeps the PaymentRequest alive until we resolve or reject the correct promise.
