7d7fcff03b ie: scan: take into account RSSI when parsing data rate 
The spec dictates RSSI thresholds for different modulation schemes, which
correlate to different data rates. Until now were were ranking a BSS with
only looking at its advertised data rate, which may not even be possible
if the RSSI does not meet the threshold.

Now, RSSI is taken into consideration and the data rate returned from
parsing (Ext) Supported Rates IE(s) will reflect that.

922e10e82c ie: add macro for calculating an IE's length 
All over the place we do "ie[1] + 2" for getting the IE length. It
is much clearer to use a macro to do this. The macro also checks
for NULL, and returns zero in this case.

8064cb599a ie: introduce IE_AKM_IS_SAE macro 
To prepare for FT over SAE, several case/if statements needed to include
IE_RSN_AKM_SUITE_FT_OVER_SAE. Also a new macro was introduced to remove
duplicate if statement code checking for both FT_OVER_SAE and SAE AKM's.

bc30c94044 ie: Add IE tags new in 802.11-2016 
Add new IEs including the Extended Element IDs, for which I make a
convention of using 256 + the actual value to differentiate from old
Element IDs.

9ceca7a521 ie: Parse GTK and IGTK subelements in FTE 
Parse the contents of the GTK and IGTK subelements in an FT IE instead
of working with buffers containing the whole subelement.  Some more
validation of the subelement contents.  Drop support for GTK / IGTK when
building the FTE (unused).
