lib, irmd: Bind AP instances to AP_subsets

This call will allow grouping AP instances of a certain AP together
which are configured identically. Adds the bind operation to dev and
updates the applications to make use of this call. Flow_alloc is now
only called with the pid and doesn't send the apn anymore.
