0e414b6c90 wifi: Enable QoS support in the backward compatibility examples 
Otherwise, HT stations send QoS data frames that cannot be received
by non-QoS stations. Also, check that the receiver supports HT
before calling GetMaxAmpduSize() with WIFI_MOD_CLASS_HT.

29cb1bfe0f wifi: Txop holds a channel access state 
This is needed because (Qos)Txop will no longer hold a current MPDU
that can be used to determine whether a frame exchange is ongoing.

2de357aac2 wifi: Add WifiTxVector::GetModulationClass for convenience 
In case the TxVector is MU, we don't need to specify any STAID
because the modulation class is unique. Getting the modulation
class through the WifiMode requires to specify the STAID instead.

2bcf750347 wifi: A queued WifiMacQueueItem stores an iterator to itself 
This allows us to dequeue packets only when they are actually
transmitted. For instance, a packet protected by RTS is dequeued
only if the CTS is received. This saves us from reinserting the
packets in the queue if CTS is missed (think of A-MPDUs, multi-TID
A-MPDUs, MU PPDUs, ...)
