cfg80211: separate internal SME implementation
The current internal SME implementation in cfg80211 is
very mixed up with the MLME handling, which has been
causing issues for a long time. There are three things
that the implementation has to provide:
* a basic SME implementation for nl80211's connect()
call (for drivers implementing auth/assoc, which is
really just mac80211) and wireless extensions
* MLME events for the userspace SME
* SME events (connected, disconnected etc.) for all
different SME implementation possibilities (driver,
cfg80211 and userspace)
To achieve these goals it isn't necessary to track the
software SME's connection status outside of it's state
(which is the part that caused many issues.) Instead,
track it only in the SME data (wdev->conn) and in the
general case only track whether the wdev is connected
or not (via wdev->current_bss.)
Also separate the internal implementation to not have
callbacks from the SME events, but rather call it from
the API functions that the driver (or rather mac80211)
calls. This separates the code better.

mac80211: always send multicast on CAB queue
If the driver advertised support for a CAB queue, then we
should put all multicast frames there, otherwise sending
them can be racy with clients going to sleep while we TX
a frame. To avoid this, always TX multicast frames on the
multicast queue.
It seems like even drivers not using the queue framework
might want to do this which would mean also moving the
IEEE80211_TX_CTL_SEND_AFTER_DTIM flag assignment, but it
also seems that drivers behave differently here so that
just moving it wouldn't be a good idea. It'd be better to
modify those drivers to use the queue framework.

cfg80211: Allow TDLS peer AID to be configured for VHT
VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current
design for TDLS is to first add a dummy STA entry before completing TDLS
Setup and then update information on this STA entry based on what was
received from the peer during the setup exchange.
In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
like this is used in AP mode to set the AID of an association station.
However, existing cfg80211 validation rules prevent this attribute from
being used with set_station operation. To avoid interoperability issues
between different kernel and user space version combinations, introduce
a new nl80211 attribute for the purpose of setting TDLS peer AID. This
attribute can be used in both the new_station and set_station
operations. It is not supposed to be allowed to change the AID value
during the lifetime of the STA entry, but that validation is left for
drivers to do in the change_station callback.
