There was a technical change between the last IETF draft version
(draft-arkko-eap-aka-kdf-10) and RFC 5448 in the leading characters
used in the username (i.e., use unique characters for EAP-AKA' instead
of reusing the EAP-AKA ones). This commit updates EAP-AKA' server and
peer implementations to use the leading characters based on the final
RFC.
Note: This will make EAP-AKA' not interoperate between the earlier
draft version and the new version.

AT_NEXT_PSEUDONYM is supposed to be included only in the Challenge
messages, not in the Re-authentication messages. This attribute was
incorrectly included in the Re-authentication messages and could have
been used to update the pseudonym state on the server without the peer
updating its state.

This commit adds a new wrapper, random_get_bytes(), that is currently
defined to use os_get_random() as is. The places using
random_get_bytes() depend on the returned value being strong random
number, i.e., something that is infeasible for external device to
figure out. These values are used either directly as a key or as
nonces/challenges that are used as input for key derivation or
authentication.
The remaining direct uses of os_get_random() do not need as strong
random numbers to function correctly.
