This patch adds a callback for the HCI_LE_Set_Advertise_Enable command.
The callback is responsible for updating the HCI_LE_PERIPHERAL flag
updating as well as updating the advertising data flags field to
indicate undirected connectable advertising.

This patch adds support for setting basing LE advertising data. The
three elements supported for now are the advertising flags, the TX power
and the friendly name.

The core specification defines 127 as the "not available" value (well,
"reserved" for BR/EDR and "not available" for LE - but essentially the
same). Therefore, instead of testing for 0 (which is in fact a valid
value) we should be using this invalid value to test if the tx_power is
available.

Since channel contexts are usually present before
stations can be added to an interface, reassign
before stations them in reconfiguration as well.

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.
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

When the driver requests a restart (reconfiguration) it
gets all the normal method calls, but can't really tell
why they're happening. Call a new restart_complete op
in the driver when the restart completes, so it could
keep its own state about the restart and clear it there.

While connected to a GO, parse the P2P NoA attribute
and pass the CT Window and opportunistic powersave
parameters to the driver.
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Parsing the P2P attributes can be tricky as their
contents can be split across multiple (vendor) IEs.
Thus, it's not possible to parse them like IEs (by
returning a pointer to the data.) Instead, provide
a function that copies the attribute data into a
caller-provided buffer and returns the size needed
(useful in case the buffer was too small.)

    cfg80211: allow registering to beacons

allowed only a single process to register for beacon events
per wiphy.  This breaks cases where a user may want two or
more VIFs on a wiphy and run a seperate hostapd process on
each vif.

This patch allows multiple beacon listeners, fixing the
regression.

This new callback can be used to tune the rate to be used to send
multicast frames.

In the current state the multicast rate can be specified on IBSS/MESH
joining only. This makes it impossible to select a custom multicast
rate when then join command is sent by an external program (e.g.
wpa_supplicant)

When userspace asks to deauthenticate and we're just
authenticated (or still authenticating) send a deauth
frame instead of deleting the auth request.

On the other hand, if we've just disassociated and
therefore deleted all our state already, drop the
deauth request because we no longer have a channel
context to send it on.
