This change reorganises the Wi-Fi MAC high classes in attempt to reduce duplication of functionality that is required for more than one of the MAC high models. A new class called RegularWifiMac has been created. This derives from the abstract WifiMac, and is parent of AdhocWifiMac, StaWifiMac, ApWifiMac, and MeshWifiInterfaceMac. The QoS and non-QoS class variants are no longer, with a RegularWifiMac attribute "QosSupported" allowing selection between these two modes of operation. QosWifiMacHelper and NqosWifiMacHelper continue to work as previously. Updates to some regression traces are necessary because the reorganisation has led to random number streams being initialised in slightly different orders and thus over-the-air timing changing.
