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).

Ignore hostapd_event_sta_low_ack for a station which has agreed to
steering by checking the agreed_to_steer flag. This flag will be set
whenever a station accepts the BSS transition request from the AP.
Without this ignoring of the LOW_ACK event, the steering in-progress
might be affected due to disassociation. In this way AP will allow some
time (two seconds) for the station to move away and reset the flag after
the timeout.

Add an option to add MBO IE to BSS Transition Management Request frame.
The MBO IE includes the transition reason code, cellular data connection
preference, and, if the disassoc imminent bit is set, it may also
include re-association retry delay. Otherwise, the re-association retry
delay should be set to zero.
The additional BSS_TM_REQ argument uses the following format:
mbo=<reason>:<reassoc delay>:<cell pref>
reason: 0-9
reassoc delay: 0-65535 (seconds; 0 = disabled)
cell pref: 0, 1, 255

hostapd control interface can now be used to request transmission of a
BSS Transition Management Request frame to a specified station.

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.

This makes it easier to trigger the ESS Disassociation Imminent
operation from different sources.
