nl80211: Split nl80211_check_bss_status() into a separate function
This allows a single scan result to be checked at a time. This is a step
towards optimizing scan result fetching without having to allocate
memory for all entries at the same time.

nl80211: Separate channel noise fetch from scan result processing
This untangles the NL80211_CMD_GET_SURVEY handler loop from
NL80211_CMD_GET_SCAN processing so that the per-channel noise
information can be fetched with a common function to a local data
structure that can then be easily used to update individual scan results
(a single BSS) instead of having to go through a full set of scan
results. This is a step towards optimizing scan result fetching without
having to allocate memory for all entries at the same time.

tests: WDS 4addr behavior on reassociation and with open and WEP
This extends the ap_wds_sta test case to cover post-reassociation case
(both with and without Authentication frame exchange) and add similar
test cases to cover open and WEP cases in addition to this existing
WPA2-PSK test case.
These cover functionality testing for the previous fix in
reassociation-without-new-authentication case. In addition, these find a
new mac80211 issue for the WEP + 4addr combination.

Fix 4addr reassociation-without-deauthentication on AP
Data connection was lost if a station reassociated without the STA entry
being cleaned up on the AP side. Fix this by moving reconfiguration of
the STA WDS parameters in association response callback to happen only
after the STA flags have been updated to associated stated.

wired: Mark some common helper functions static
These are used only within driver_wired_common.c now at the end of the
refactoring changes, so there is no need to make these helper functions
available outside driver_wired_common.c.

macsec_linux: Add a driver for macsec on Linux kernels
This uses libnl3 to communicate with the macsec module available on
Linux. A recent enough version of libnl is needed for the macsec.h file
(which is not yet available in a formal libnl release at the time of
this commit).
