Commit 1057d8aa74 changed the device interface creation logic
from being unconditional inside netdev.c to instead use NETDEV_WATCH_*
events. However, this broke the assumption that the device interface
was created before all others. The effect is that the scan_wdev_add
might no longer be called prior to station interface being created. Fix
this by moving scan_wdev_add/remove calls to netdev.c instead.

Save the source frame type in struct scan_bss as it may affect how some
of the data in the struct will be parsed. Also replace the P2P IE
payload data in that struct with a union containing pre-parsed p2p
attributes corresponding to the frame type.
This means users don't have to call the parsers in p2putil.c on that
data, which wouldn't have worked anyway because those parsers assume
input is the raw IE sequence rather than just the "payload".
All these functions free up the resources used by the struct but don't
free the struct itself (allowing it to be static) so rename the
functions to avoid confusion.
The kernel sends NL80211_ATTR_SCAN_START_TIME_TSF with CMD_TRIGGER and
RRM requires this value for beacon measurement reports.
The start time is parsed during CMD_TRIGGER and set into the scan request.
A getter was added to obtain this time value for an already triggered
scan.
After making the change, the SCAN_ABORTED case was cleaned up a bit to
remove the local scan_request usage in favor of the one used for all the
other cases.
Create and destroy the device state struct and the DBus interfaces in a
way more similar to the Station, AdHoc and AP interfaces. Drop
netdev_get_device() and the device specific code in netdev that as far
as I can tell wasn't needed.
Check the iftype before registering ANQP on new interface.
Not that the check here and in rrm.c (which already checks the iftype)
may need to be extended to run on NETDEV_WATCH_EVENT_UP because a device
could be created with a different iftype and then have the iftype changed
before powering up.
The RCPI value was using floating point values as per the spec. But instead
we can just use the signal strength coming from the kernel in mili mdm and
scale the hard coded values by a factor of 100.
Beacon requests can specify a scan duration, and set a flag which makes
this duration mandatory. The kernel supports both these values for scan
requests so we no longer need to reject requests which contain these.
Drivers which do not support EXT_FEATURE_SET_SCAN_DWELL will ignore the
duration value, but if duration mandatory is set we must reject the
request.
The kernel allows a scan duration and duration mandatory flag to be
set in scan requests. RRM requests can contain these values so they
have been added to scan_parameters.
Scanning with drivers which do not support EXT_FEATURE_SET_SCAN_DWELL
will not include these values in scan requests.
This test made it past the initial refactor to use HostapdCLI with the
'config' parameter. This avoids the need to iterate the hostapd map in
the actual test.
These two processes are executed per-test so they can be passed the
test name and have the logs stored only in tests that actually need
them rather than at the top level.
If a scan is requested during the middle of a connection we should
return busy instead of attempting the scan. The kernel ends up coming
back with not supported in this case, which is misleading and
difficult to debug.
The module framework was changed to call the module exit functions in
the reverse order as the init functions. This uncovered/caused known
networks to try and free the network_info structures after hotspot had
already freed them. Since known networks clean up the network_info's
anyways, we don't actually need hotspot to do any cleanup.
