Add all the handling to do NAN synchronization on 2.4 GHz including
sending out beacons. With this, the mac80211_hwsim NAN device also works
when used in conjunction with an external medium simulation.
Note that the TSF sync is not ideal in case of an external medium
simulation. This is because the mactime for received frames needs to be
estimated and the simulation may not update the timestamp of beacons
to the actual time that the frame was transmitted.
The implementation has an initial short phase where it scans for
clusters. This facilitates cluster joining and avoids creating a new
cluster immediately, which would result in two cluster join
notifications. It does not scan otherwise and will only see another
cluster appearing if a discovery beacon happens to be sent during the
2.4 GHz discovery window (DW).

When considering both NPCA and DBE, it can appear that the

with DBE to 160 MHz:
| primary channel
| NPCA primary channel
| |
V V
| p | | n | | | | | |
| BSS channel |
| DBE channel |
Now the NPCA primary channel is in the same half as the primary

invalid as a puncturing bitmap when considering the overall
channel.

Refactor the NAN timer to more closely track the where in the NAN
schedule the device currently is. Do this by having an hrtimer that
fires at the start of every slot.
For now continue to update the current channel at the start of the DW.
In the future, the correct channel according to the schedule should be
used everywhere.
This is in preparation to more accurately simulate more of the NAN
logic.

It is easy to calculate the next target beacon transmission time (TBTT)
based on the current TSF and the beacon interval. Use this method to
calculate the time to the next beacon.
With this, the bcn_delta variable can be removed and drift over time due
to the timer firing late is fully avoided.

By delegating writing the timestamp into beacons and probe responses, we
can remove the abs_bcn_ts from the global data and still avoid any time
offset issues. This also seems conceptually closer to "real" hardware
where the timestamp will be written late in the TX path.
Move sending the SKB to the monitor interface to happen later, so that
the frame timestamp has the value filled in by mac80211_hwsim.

The mac80211_hwsim base time for the simulation of the TSF was based on
the real time of the system. This clock is subject to unexpected
changes. Switch it to use boottime which is always monotonic and also
continues to run through times where the system is suspended.
Also change the function name from tsf_raw to sim_tsf to better
differentiate between the TSF of the mac and the TSF base of the
simulation.

Having everything in one file for mac80211_hwsim is starting to get a
lot and it will be even worse if we implement more parts of NAN. Split
the NAN implementation into separate files to improve the code
structuring.
