The original version of these functions would modify the address sent in, meaning that the caller would usually need to copy the address first. This change makes the original a const, and puts the resulting masked address into a new arg (which could point to the same virSocketAddr as the original, if the caller really wants to modify it). This also makes the API consistent with virSocketAddrBroadcast[ByPrefix].
