This patch extends the existing decryption support for WPA to also handle rekeys by checking each decrypted packet for a 4-way-handshake. Rekeys can be used for WPA-PSK, but are more common with WPA-Enterprise (WPA-EAP). For decrypting WPA-EAP secured packets the user must provide all used PMK's of the connection (aka PSK's) as WPA-PSK 32 byte hex values to wireshark via the existing interface. (The capture must have all 4-way-handshakes included also, starting with the first unencrypted one.) Every decrypted unicast packet will habe the used PMK and TK shown in the CCMP/TKIP section below the key index in the GUI. Group packets will display the GTK instead. Additionally this fixes a small issue with group rekey handling, so every packet can be selected in the GUI in random order, removing the need to manually find the correct group keying packets prior to that. It was tested primary with WPA-CCMP, but TKIP is also working. One section in the code touch bluetooth 802.1X support. It should do exactly the same, but will now also examine all decypted packets for rekeys.
