62542e5fb9 wifi: WifiMacQueueItem does not keep a pointer to the queue it is stored into 
Instead, it keeps the AC index associated with the queue it is stored into

d04a17af6f wifi: Make WifiMacQueue::TtlExceeded public 
so that other components can easily remove MPDUs with expired
lifetime and fire the Expired trace source.

edcd9a6909 wifi: Cleanup WifiMacQueue 
1. MPDUs with expired lifetime are already discarded:
   - when a QosTxop releases/requests the channel
   - when we check if there are pending BlockAckReq frames
   hence, it is useless (and sometimes troublesome) to check
   for MPDUs with expired lifetime at every packet dequeue
2. Dequeue{ByTid, ByAddress, ...} were not used and hence
   removed (one can use a Peek* method and then Dequeue())
3. Given that a WifiMacQueueItem stores an iterator, add a
   Dequeue method (the only one in addition to the default one)
   that receives a WifiMacQueueItem and dequeues it in constant time

6bce3d9916 wifi: Replace aggregated MSDUs with the A-MSDU upon aggregation 
So far, when A-MSDU aggregation is performed, MPDUs containing the
constituent MSDUs are kept in the queue until the MPDU containing
the A-MSDU (which is kept out of the queue) is transmitted.
Now, as soon as A-MSDU aggregation is performed, MPDUs containing
the constituent MSDUs are dequeued and the MPDU containing the
A-MSDU is enqueued in their place.

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, ...)

fe561a82ca wifi: fix iterator invalidation in WifiMacQueue::Insert 
If pos == begin(), it may be invalidated before inserting if DROP_OLDEST
policy is used and queue is full.

Add fix for this case and a test for it.

f781366d2e Fix compilation with Clang 3.2 and newer versions, including Apple Clang 5.0 
Clang 3.2 requires all class members to be used in the code; this patch either removes class members that are not used or adds NS_UNUSED/NS_UNUSED_GLOBAL around them. Thanks to Andrey Mazo and Tommaso Pecorella for review.
