Subject: mac80211_hwsim: allow using channel contexts

To use mac80211_hwsim for testing channel contexts it
has to support them, and for that it has to support
hw scan and hw-remain-on-channel.

Since it's pure software, the off-channel activities
are really not off-channel but listening and sending
on a second channel. Also, the multi-channel isn't
really doing TDM, it's just on both channels at the
same time.

For testing purposes, you can specify the number of
concurrent channels with a module parameter, it is
set to one by default. When set to two or more, the
userspace API for wmediumd is disabled as it has no
provisions for multi-channel yet.

Subject: cfg80211: allow per interface TX power setting

The TX power setting is currently per wiphy (hardware
device) but with multi-channel capabilities that doesn't
make much sense any more.

Allow drivers (and mac80211) to advertise support for
per-interface TX power configuration. When the TX power
is configured for the wiphy, the wdev will be NULL and
the driver can still handle that, but when a wdev is
given the TX power can be set only for that wdev now.

Subject: mac80211: clarify interface iteration and make it configurable

During hardware restart, all interfaces are iterated even
though they haven't been re-added to the driver, document
this behaviour. The same also happens during resume, which
is even more confusing since all of the interfaces were
previously removed from the driver. Make this optional so
drivers relying on the current behaviour can still use it,
but to let drivers that don't want this behaviour disable
it.

Also convert all API users, keeping the old semantics
except in hwsim, where the new normal ones are desired.
