Some changes were needed to this, but I was now able to complete
EAP-TTLS authentication with Funk Odyssey server. I needed to use an
external RADIUS server and forwarding for the inner EAP-MD5 part because
Odyssey did not seem to allow inner EAP to be processed locally. Anyway,
the TTLS part seemed to now work correctly.

I did this testing remotely with the supplicant encapsulating everything
in RADIUS messages. I did not verify whether WPA/WPA2 would have
succeeded after this. Anyway, the derived key from EAP-TTLS seemed to
match in Odyssey and wpa_supplicant logs, so everything should be fine
now in the CVS snapshot.
