A similar change was previously done for Probe Response frames, but the
Beacon frame case was missed. Fix this to remove the VHT elements also
from Beacon frames on the 6 GHz since the relevant information is
included only in the HE elements on that band.

Split the IEs from WPA authenticator state machine into separately added
IEs so that the exact location between these and other elements can be
controlled. This fixes the location of MDE and RSNXE in Beacon and Probe
Response frames. In addition, this swaps the order of BSS Load and RM
Enabled Capabilities elements in Beacon frames to get them into the
correct order (which was already used for Probe Response frames).
Furthermore, this fixes the buffer end checks for couple of elements to
make the implementation more consistent (though, in practice, there is
no impact from this since the old size limit was smaller than needed,
but still sufficiently large to have room for these).

SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.
Remove the parts of SMPS support that involve the AP using it locally.
In practice, this reverts the following commits:
04ee647d58 ("HT: Let the driver advertise its supported SMPS modes for AP mode")

The HE capabilities are no longer per PHY but per iftype on this
specific PHY. It is therefore no longer enough to just parse the AP
capabilities.
The he_capabilities are now duplicated to store all information for
IEEE80211_MODE_* which hostap cares about. The nl80211 driver fills in
this information when the iftype supports HE. The rest of the code still
only uses the IEEE80211_HE_AP portion but can be extended later to also
use other HE capabilities.

This adds support for nl80211 NL80211_CMD_SET_MULTICAST_TO_UNICAST
command.
By setting the new hostapd configuration option multicast_to_unicast=1,
hostapd configures this AP to perform multicast to unicast conversion.
When enabled, all multicast packets with ethertype ARP, IPv4, or IPv6
(possibly within an 802.1Q header) will be sent out to each station once
with the destination (multicast) MAC address replaced by the station's
MAC address. Note that this may break certain expectations of the
receiver, e.g., the ability to drop unicast IP packets encapsulated in
multicast L2 frames, or the ability to not send destination unreachable
messages in such cases.
This also does not implement Directed Multicast Service (DMS).

A weakness in the initial client taxonomy mechanism is from storing both
the Probe and Associate in struct sta_info. struct sta_info is created
after a client associates (or starts authentication frame exchange),
which means that any Probe Request frames sent prior to association are
not retained. The Associate Request frame has to be seen, and then
another Probe Request frame after association, before we have a
signature for the client.
Most clients send lots of Probe Request frames (lots and lots and lots
of Probes, actually), but a few do not. ChromeOS is notably sparing in
sending Probe Request frames, it can take a long time before a signature
for a ChromeOS device is available.
Store the most recent Probe Request frame in struct hostapd_sta_info
tracking list. When a struct sta_info is created, move the Probe Request
frame information from struct hostapd_sta_info to struct sta_info.
