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.

Removed "key prefix" need within GUI so it's a little more intuitive (because
that's what this bug is complaining about). Slight backwards compatibility
issue with UAT (because key prefix was in previous keys), but all development
(including fix for BUG 1123 that created UAT) has just been on SVN and not
released.
Also adjusted AirPCap (airpcap_loader.c) to account for the lack of "key
prefix".
Addressed some memory leaks/excess string creation.

the lack of SSID). Wildcarding combines the passphrase with the last
seen SSID and attempts decryption. The last-seen stack is only one
element tall, which means it may get clobbered on busy and diverse
networks. We can expand it if needed.
Make internal functions static in airpdcap.c. Rearrange the
AIRPDCAP_KEY_ITEM struct so that the passphrase and SSID don't get
clobbered when we set our PSK.

functions to strutil. Use GByteArrays to store SSIDs for decryption,
and let the user specify arbitrary byte strings using percent-encoded
strings. We should probably add percent encoding for pass phrases as
well, so you can escape the ":" character.
Move the key struct key conversion utilities to airpdcap.c, and remove
duplicate code from packet-ieee80211.c. Fix a lot of indentation.
