This uses the new nl80211 attributes to allow the connect command to
provide bssid and freq hints to the driver without limiting roaming to
the specific BSS/frequency. This can be used by drivers that perform
internal BSS selection (WPA_DRIVER_FLAGS_BSS_SELECTION) as a candidate
for initial association.

Commit b1f625e0d8 extended
ap_scan_as_station to be able to distinguish between AP and P2P GO
iftypes. However, it did this in a way that completely lost the original
mode because drv->nlmode had already been replaced with the station
mode. Fix this by storing the correct old mode.

Commit 795baf773f ('hostapd: Filter
channel list updated events after country code change') uses the
EVENT_CHANNEL_LIST_CHANGED data pointer, but it updated only one of the
callers to provide that data. NL80211_CMD_REG_BEACON_HINT event was
still sending the event without the initiator data and resulted in NULL
pointer dereference, e.g., if a scan was run while hostapd was running
and the driver was in world roaming state and enabled a channel for
active scans.

The original RSSI filter semantics for scheduled scan were
really confusing - a separate matchset was created, but it
wasn't actually treated as a separate matchset in the kernel
but rather used as the global RSSI value. The RSSI matchset
thus behaved like an RSSI filter outside of the matchsets,
being ANDed rather than ORed (as normal between matchsets.)
To make this less confusing, I changed the kernel API a bit
to actually treat the RSSI inside each matchset properly,
but keeping it compatible with the old approach by using a
matchset with only an RSSI value as the default for all the
other matchsets, and adding it as a separate matchset only
if it's the only one.
The proper way for wpa_supplicant to do this then would be
to add the RSSI to each SSID matchset, and only add another
matchset without SSID if there's none with.
However, to keep compatibility with older kernels, always
keep the non-SSID matchset and only add the RSSI to all the
other matchsets. This gets close to the desired behaviour,
the only difference would be that we shouldn't add the RSSI
matchset if there are others, but stays compatible with old
and new kernels, as new ones ignore the RSSI-only matchset
if there are others and those others have an RSSI.

It is possible for channel switch notification to be missing channel

iface->conf->secondary_channel being set to 0. This in turn made
subsequent DFS-triggered CSA to fail due to invalid frequency

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

Currently these three steps runs for each event.
1. get buffer size via system
2. allocate a memory for event
3. free the memory
The wpa_supplicant receives 4 events from boot to be connected.

If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).
In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can
be used to clear all BSS entries from both the driver and
wpa_supplicant.

If Action frame registration in nl80211_mgmt_subscribe_non_ap() failed
for any frame type, the previous implementation skipped
nl80211_mgmt_handle_register_eloop() call. This is not desirable since
none of the Action frame types could be received and even worse, the
following nl80211_destroy_eloop_handle() call for nl_mgmt would likely
result in crashing the process due to the ELOOP_SOCKET_INVALID XOR
operation. This could be triggered at least in a P2P group interface
startup failure case.

Previously, it was possible for bss_info_handler() to end up dropping a
newer scan result entry if there were two entries with the same BSSID
and SSID (i.e., only frequency was different) and we were not associated
with either. This could happen, e.g., in some P2P use cases where device
discovery may happen on different channels. Fix this by checking the age
of the scan entries as well to prefer the most recent response.

The option of handling upper layer P2P management operations within the
driver/firmware was originally planned to be used with wpa_supplicant,
but this has not really happened and there is no clear sign of this
being needed in the near term either. This functionality has not been
completed and it is certainly not being kept up-to-date or tested. As
such, it is best to remove it for now and if this or something similar
is needed in the future, it can be brought back once a clear need for it
has been demonstrated first.

This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

frames, like FT Action. This broke FT-over-DS when PMF is enabled with

for receiving management frames).
