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).

Add a mechanism to configure the candidates for BTM query candidate list
manually. This can be used to verify AP behavior for various candidates
preferences.
usage:
wnm_bss_query <reason> [neighbor=<BSSID>,<BSSID information>,
<operating class>,<channel number>,
<PHY type>[,<hexdump of optional subelements>]]

Add support for rejecting a BSS transition request using MBO reject
reason codes. A candidate is selected or rejected based on whether it is
found acceptable by both wpa_supplicant and the driver. Also accept any
candidate meeting a certain threshold if disassoc imminent is set in BTM
Request frame.

Add an option to configure a candidate list to BSS transition query
("list" as the second argument to WNM_BSS_QUERY). The candidate list is
built from the available scan results. If no updated scan results (< 10
sec) are available, the command fails.

If the last scans are recent (for now, less than ten seconds old), use
them instead of triggering a new scan when a BSS Transition Management
Request frame is received. As a fallback, allow a new scan to be
triggered if no matches were found.

When the list of preferred transition candidates is received, use the
identified channels to optimize the following scan so that no time is
wasted on other channels.

There is no need to use a separately allocated data structures for this.
A bitfield indicating which information is present and variables within
struct neighbor_report are simpler to use and more efficient.

The structures are all allocated, so the pointer can be compared to NULL
to determine whether the subelement was present.

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.

The new control interface command can be used to send a
BSS Transition Management Query frame to the current AP.

The optional tfs_req=<hex dump> parameter can be added for the wnm_sleep
command to specify the TFS request element to use in the WNM-Sleep Mode
Request frame.
