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.

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.

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.

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

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.
