Instead of going through the configuration exchange, reject invalid
legacy configurator parameters explicitly. Previously, configuring
legacy (psk/sae) parameters without psk/pass resulted in a config object
that used a zero length passphrase. With this change, that config object
is not sent and instead, either the initialization attempts is rejected
or the incoming initialization attempt is ignored.

BSS additional/removal cases were not considered at all in the previous
implementation of hostapd configuration file reloading on SIGHUP. Such
changes resulted in num_bss values getting out of sync in runtime data
and configuration data and likely dereferencing of freed memory (e.g.,
when removing a BSS).
Fix this by forcing a full disable/enable sequence for the interface if
any BSS entry is added/removed or if an interface name changes between
the old and the new configuration.

Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".
This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

Previous implementation ended up triggering PMF check for previous
association and SA Query procedure incorrectly in cases where there is a
STA entry in hostapd, but that STA is not in associated state. This
resulted in undesired temporary rejection of the association with status
code 30.
This ended up breaking OWE group negotiation when PMF is in use since
the check for the OWE group would have happened only after this earlier
PMF check and rejection (i.e., the station got status code 30 instead of
the expected 77).
For example, when the AP is configured with OWE group 21 and a station
tries groups 19, 20, and 21 (in this sequence), the first two
Association Request frames should be rejected with status code 77.
However, only the first one got that status code while the second one
got status code 30 due to that issue with PMF existing association
check.
Furthermore, hostapd was continuing with SA Query procedure with
unencrypted Action frames in this type of case even though there was no
existing association (and obviously, not an encryption key either).
Fix this by checking that the STA entry is in associated state before
initiating SA Query procedure based on the PMF rules.

When removing an interface, hostapd_bss_deinit() frees all associated
STAs. If any of the stations is 40MHz intolerant, the cleanup invokes
ht40_intolerant_remove(), that in turn registers a 20->40MHz transition
timer for the last station (ap_ht2040_timeout() function). That timer is
never canceled; once it executes, the interface is gone, most likely
resulting in a segfault when referencing it.
While hostapd_interface_deinit() cancels the transition timer, it does
so before cleaning up STAs. Move the cancellation after STA cleanup to
cancel any timer that was registered during that operation.

A new SAE Commit message should not be allowed to drop an existing STA
entry since the sender of that Commit message cannot be authenticated
before receiving the Confirm message. This is important in particular
when PMF is used since this would provide a potential new path for
forcing a connection to be dropped.
Fix this by allowing a new SAE Authentication instance to be started
when the old instance is in Accepted state and the new Commit message
does not use the same peer-scalar value (checked in
sae_parse_commit_scalar()). When PMF is used, the AP will use SA Query
procedure when receiving the (Re)Association Request frame. In theory,
that step could be skipped in case of SAE Authentication since the
non-AP STA is demonstrating knowledge of the password. Anyway, there is
no allowance for that exception in the IEEE 802.11 standard, so at least
for now, leave this using SA Query procedure just like any other PMF
case.

2. hostapd_cli -p /var/run/hostapd chan_switch 10 5200 center_freq1=5200 \

This is since VHT config from chan_switch is processed only for
bandwidths 80 and above (80P80, 160) and for VHT20, VHT40 cases, only
NLA chan type and chan width are updated.
There is no NL attribute for determining if it is HT or VHT for
bandwidths 20 & 40 and currently they are updated as HT20, HT40 (+ or -
depending on offset). Same is notified back via
NL80211_CMD_CH_SWITCH_NOTIFY.
Instead of adding new NL attribute for tracking HT/VHT enabled config,
we are adding new hostapd VHT config parameter to save the chan_switch

When the channel time is zero the interference factor calculation falls
under divide by zero operation which results in invalid (NaN =
not-a-number) interference factor value. This leads to wrong ideal
channel selection in ACS during the scenario described below.
Scenario:
In VHT80 mode, the channel 36 (first channel) gets the channel time as
zero which causes the interfactor factor to be an invalid number (NaN).
Any operations (like addition, mulitplication, divide, etc.) with NaN
value results in a NaN value, so that average factor for the primary
channel 36 got the invalid value (NaN). Since channel 36 is the first
channel, ideal factor is assigned as NaN in the first iteration. The
following iteration condition check (factor < ideal_factor) with a NaN
value fail for all other primary channels. This results in channel 36
being chosen as the ideal channel in ACS which holds a NaN value.
Logs:
