If WNM is enabled for the build (CONFIG_WNM=y), add BSS max idle period
information to the (Re)Association Response frame from the AP and parse
this information on the station. For SME-in-wpa_supplicant case, add a
timer to handle periodic transmission of the keep-alive frame. The
actual request for the driver to transmit a frame is not yet
implemented.

In some situations it might be benefical to send a unicast frame without
the need for getting it ACKed (probe responses for example). In order to
achieve this add a new noack parameter to the drivers send_mlme callback
that can be used to advise the driver to not wait for an ACK for this
frame.

hapd->time_adv cannot really be NULL if hostapd_update_time_adv()
returns success, but this construction seems to be too difficult
for some static analyzers. While this change is not really needed
in practice, it makes it easier to go through warnings from such
analyzers.

The Query Response Length Limit is not allowed to be zero when
this is sent by the AP. Use 0x7F to indicate that the limit is
based on maximum number of GAS fragments.
This is the first step in allowing SA Query mechanism in hostapd to be
used with drivers that implement authentication and association MLME/SME
(i.e., do not use ieee802_11.c).
