This adds debug information from wlantest into pcapng frame comments to
make the information more convenient to use, e.g., in Wireshark.

The WPA/RSN IE in EAPOL-Key 2/4 is more reliable than the one in
(Re)Association Request frame. Update the STA info base don the
EAPOL-Key frame so that the correct cipher information is used
even if the (Re)Association Request frame is missing or corrupted
in the capture.

KEK from TPTK needs to be used instead of from PTK when processing
rekeying case similarly to what was already done with KCK.

Use a temporary PTK buffer during 4-way handshake when rekeying PTK
so that the new EAPOL-Key frame MIC values are checked against the
new PTK and frames are decrypted using the old PTK. Take the new
PTK into use once msg 4/4 is processed and clear RSC counters at
that point (including moving of RSC update to avoid setting RSC
based on the msg 4/4).
In addition, add a workaround to handle supplicant implementations that
set Secure bit to one during PTK rekeying 4-way handshake in msg 2/4.
This was previously assumed to be msg 4/4, but the key data contents
can be used to figure out whether this is msg 2/4 even if the Secure
bit is set to one.
