Subject: mac80211_hwsim: fix memory leak on netlink TX failure

If the packet can't be delivered to userspace (at all or
quickly enough) then it can leak - fix that.

Subject: mac80211-hwsim: Add support for HWSIM_ATTR_DESTROY_RADIO_ON_CLOSE

Add support for new attribute HWSIM_ATTR_DESTROY_RADIO_ON_CLOSE
which can be set by the user space component. The attribute
will cause the kernel to destroy all those radios that were
created by a process if that process dies. The old behaviour
i.e., radios are persistent is still the default.

Subject: mac80211-hwsim: Provide multicast event for HWSIM_CMD_NEW_RADIO

When adding new radio via HWSIM_CMD_NEW_RADIO then listeners on the
multicast group "config" are informed.

While at it, refactor the configuration parameters to be able to
pass them directly and have fewer function arguments.

Subject: mac80211: replace restart_complete() with reconfig_complete()

Drivers might want to know also when mac80211 has
completed reconfiguring after resume (e.g. in order
to know when frames can be passed to mac80211).

Rename restart_complete() to a more-generic reconfig_complete(),
and add a new enum to indicate the reconfiguration type.

Update the current users with the new prototype.
