[v3,0/3] support ftm responder configuration/statistics

Message

Currently ftm_responder parameter in hostapd.conf is only used for fine
timing measurement (FTM) capability advertisement and actual control of
the functionality is with low-level device/driver. This leads to confusion
to the user when the capability advertisement is different from actual FTM
responder functionality.

For example, FTM responder capability advertisement is set to 'enabled',
but the functionality is disabled or not supported by the driver.

The patch set allows userspace to enable FTM responder functionality
with the addition of new Netlink flag attribute NL80211_ATTR_FTM_RESPONDER
with configurable lci/civic ocation parameters. Also extended feature flag
is added for the drivers to advertise the support. Setting the flag to
enable FTM responder would imply that AP responds to all FTM requests.
Default is considered to be disabled.

changes in V3:
 - fixed the ambiguous ftm responder disable case to be not supported

changes in V2:
- updated version number
- rebased patches
