dea0d8ee29 RADIUS: Fix a copy-paste error in variable name
MS-MPPE-Recv-Key generation in radius_msg_add_mppe_keys() used incorrect
function argument (send_key_len; should be recv_key_len) when allocating
a temporary buffer. Fix this by using the correct argument.

The only caller of the function uses the same length for both
send_key_len and recv_key_len, so this copy-paste error did not result
in any difference in the behavior.

b031338cf0 Add preliminary RADIUS dynamic authorization server (RFC 5176)
This adds the basic DAS mechanism to enable hostapd to be configured
to request dynamic authorization requests (Disconnect-Request and
CoA-Request). This commit does not add actual processing of the
requests, i.e., this will only receive and authenticate the requests
and NAK them regardless of what operation is requested.

05ab9712b9 Allow WPA passphrase to be fetched with RADIUS Tunnel-Password attribute
This allows per-device PSK to be configured for WPA-Personal using a
RADIUS authentication server. This uses RADIUS-based MAC address ACL
(macaddr_acl=2), i.e., Access-Request uses the MAC address of the
station as the User-Name and User-Password. The WPA passphrase is
returned in Tunnel-Password attribute in Access-Accept. This
functionality can be enabled with the new hostapd.conf parameter,
wpa_psk_radius.

Implements the Chargable-User-Identity (CUI), as defined in RFC 4372.
Option "-i" causes the eapol_test to send a NUL CUI - which is a request to
send a CUI back. Capital "-I" allows to specify the value of the CUI.
This has been defined for cases where the client wants to reauthenticate.
