This adds flags field which may be used to mark frequency not available

In order to get more details about each frequency we will need to set
NL80211_ATTR_SPLIT_WIPHY_DUMP in the future. This will result in our
callback being called multiple times. Modify it to support such a
scenario:
1) Start putting new frequencies after the last set one
2) Make sure that attribute is set before iterating it

 - introduce a new nl80211_request() which combines nl80211_msg() with
   nl80211_send() to simplify calling code

 - always invoke nl80211_free() in nl80211_send() and remove explicit
   nl80211_free() invocations in callers

 - back out early on netlink errors in functions performing multiple
   calls, e.g. when fetching scan results

Adjust nl80211_send() to propagate errors back to the caller and do not
free message and callbacks in send error case anymore since all callsites
immediately invoke nl80211_free() anyway.

Use the same logic as the command line interface for reporting the used WPA
ciphers. Instead of printing the intersection of pairwise and group ciphers,
report both group and pairwise ciphers.

This fixes a case where a connection which uses CCMP for pairwise and TKIP
as groupwise cipher is getting reported as using the NONE cipher.

linking with libuci means we need to link with libblobmsg_json, libjson-c and
libubox. Sinc e we do not use pkg-config or something equivalent, we need to
specify all dependencies.

If the first attempt to lookup the phy index by the path value fails, retry to
find the index within the platform/ subdirectory to follow the logic used by
the mac80211 package.

With the mac80211 commit d55d0d598e66 ("nl80211: put current TX power in
interface info") it is possible now to get TX power using nl80211. As we
don't really support any wext-only drivers it doesn't make sense to
leave wext as a fallback.

The old nl80211_hostapd_info() used a global static buffer which was not
properly zeroed on subsequent invocations, leading to misreported encryption
values when querying multiple radios or radious with multiple vifs.

Also rework and simplify the control socket code for wpa_supplicant by
splitting status query and scan handling.
