The reauth_id prefix can be used to determine which AKA version is used,
so there is no need to store the aka_prime information in a separate
field.

If hostapd is built and configured to use SQLite database, store
EAP-SIM/AKA reauth data into the database to allow this to persist
over hostapd restarts.

This allows hostapd to use an SQLite database for storing EAP-SIM/AKA
pseudonyms over process restarts. CONFIG_SQLITE=y build option adds
support for this and the SQLite database file is specified in eap_sib_db
configuration parameter.

The previous implementation was able to re-open the connection to an
external program (e.g., hlr_auc_gw) when needed, but required the
connection to be available during startup. Extend this to allow the
initial failure, so that hlr_auc_gw can be started after hostapd.

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.

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.
