mac80211: add a single-transaction driver op to switch contexts
In some cases, when the driver is already using all the channel
contexts it can handle at once, we have to do an in-place switch
(ie. we cannot afford using an extra context temporarily for the
transaction). But some drivers may not support switching the channel
context assigned to a vif on the fly (ie. without unassigning and
assigning it) while others may only work if the context is changed on
the fly, without unassigning it first.
To allow these different scenarios, add a new driver operation that
let's the driver decide how to handle an in-place switch.

Also, add the new get_expected_throughput() member

able to query the RC algorithm (this patch provides an
implementation of this API for both minstrel and
minstrel_ht).
The related member in the station_info object is now

mac80211: add pre-RCU-sync sta removal driver operation
Currently, mac80211 allows drivers to keep RCU-protected station
references that are cleared when the station is removed from the
driver and consequently needs to synchronize twice, once before
removing the station from the driver (so it can guarantee that
the station is no longer used in TX towards the driver) and once
after the station is removed from the driver.
Add a new pre-RCU-synchronisation station removal operation to
the API to allow drivers to clear/invalidate their RCU-protected
station pointers before the RCU synchronisation.
This will allow removing the second synchronisation by changing
the driver API so that the driver may no longer assume a valid
RCU-protected pointer after sta_remove/sta_state returns.
The alternative to this would be to synchronize_rcu() in all the
drivers that currently rely on this behaviour (only iwlmvm) but
that would defeat the purpose.

mac80211: add min required channel definition field
Add a new field to ieee80211_chanctx_conf to indicate
the min required channel configuration.
Tuning to a narrower channel might help reducing
the noise level and saving some power.
The min required channel definition is the max of
all min required channel definitions of the interfaces
bound to this channel context.
In AP mode, use 20MHz when there are no connected station.
When a new station is added/removed, calculate the new max
bandwidth supported by any of the stations (e.g. 80MHz when
80MHz and 40MHz stations are connected).
In other cases, simply use bss_conf.chandef as the
min required chandef.
Notify drivers about changes to this field by calling
drv_change_chanctx with a new CHANGE_MIN_WIDTH notification.

mac80211: don't assume channel is set in tracing
With the move to multi-channel and away from
drv_config(), hw.conf.channel will not always
be set, only for devices using the current API
instead of the new channel context APIs. Check
the channel is set before adding its frequency
to the trace data.
Also break some overly long lines in the code.

mac80211: support P2P Device abstraction
After cfg80211 got a P2P Device abstraction, add
support to mac80211. Whether it really is supported
or not will depend on whether or not the driver has
support for it, but mac80211 needs to change to be
able to support drivers that need a P2P Device.

mac80211: add time synchronisation with BSS for assoc
Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.
To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.
Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

mac80211: add TX prepare API
Some drivers require setup before being able to send
management frames in managed mode, in particular in
multi-channel cases.
Introduce API to allow the drivers to do such setup
while being able to sleep waiting for the setup to
finish in the device. This isn't possible inside the
TX call since that can't sleep.
A future patch may also restructure the TX retry to
wait for the driver to report the frame status, as
suggested by Arik in

mac80211: trace debug messages
It can be very useful to have all debug messages
available when debugging, but hard to correlate
between different sources, so add a trace event
for all mac80211 debug messages.
