the effective Mesh ID so we need to fetch those from ubus state info.

The wpa_supplicant control socket might reply with "FAIL-BUSY" when
attempting to start a scan while another scanning process is already
running, back out early in this case.

Using average of previous average and the next value is highly
imprecise. E.g. for values 20, 20, 20, 180 it would result in /average/
of 100 (instead of 60). Fix it by storing & using an info of how many
samples were used for the previous calculation.

cfg80211 allows drivers to announce the to-be-expected layer-2 datarate
using the NL80211_STA_INFO_EXPECTED_THROUGHPUT field.
This information is useful as a metric for user-space routing daemons,
so grab it via nl80211 and make it available in both C and Lua APIs,
and show expected throughput on CLI interface assoclist.

Drivers may abort a scan by calling cfg80211_scan_done() with a struct
cfg80211_scan_info that sets aborted to true.

To avoid blocking forever consider both NL80211_CMD_NEW_SCAN_RESULTS
and NL80211_CMD_SCAN_ABORTED when waiting for scan results.

Tested with Broadcom's bcmdhd driver.

Extend the nl82011_wait() function to accept multiple command numbers.

This is useful to wait for different possible results, e.g. either
NL80211_CMD_NEW_SCAN_RESULTS or NL80211_CMD_SCAN_ABORTED.

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

Signed-off-by: Jo-Philipp Wich <jo@mein.io>

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.

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.
