1b72fe9713 eap: Add eap event_func
This is used to get arbitrary information out of the EAP method.  Needed
for EAP-WSC to signal credential information obtained from the peer.

Other uses include signaling why EAP-WSC failed (e.g. invalid PIN, etc)
and processing of M2D discovery messages.  The information in M2Ds might
be useful to external clients.

baf72d7f86 eapol: Move to a single PAE socket

316752c5e4 ie: Error in tlv_iter_next if no space to length byte
When parsing the EAPoL-Key key data field we don't strip the 0xdd /
0x00 padding from the decrypted data so there may be trailing padding
after the IE sequence and valgrind will report an invalid read of the
length byte.  Same thing may happen if we're sent garbage.

c0de9d1790 eap-wsc: optionally load IV1 & IV2 for debugging

9a47f98ccd eap-wsc: Store M2 for future use
We need quite a bit of attributes of M2 for the duration of the WSC
handshake.  Most importantly, we need to use the peer's public key when
processing M4 and M6.  RegistrarNonce is also needed for generating any
ACK/NACK messages as needed.

Also, peer's device attributes such as Model, Manufacturer, etc might be
useful to report upon successful handshake.

39d6acb07d eap-wsc: Don't store AuthKey | KeyWrapKey | EMSK
AuthKey is already uploaded into auth_key_hmac.  KeyWrapKey is now
uploaded into the AES-CBC(128) cipher.  We currently have no use for
EMSK.

So we no longer need to keep the wsc_session_key structure around.

2cbbcb7434 eap-wsc: Load settings related to DevicePassword
DevicePassword is the PIN, either static, dynamically generated or
entered by the user.  For PushButton mode, DevicePassword is set to
'00000000'.  It can also be provided via external means, such as NFC.

This patch allows DevicePassword to be externally configured into the
EAP-WSC layer.  Optionally, the secret nonce values can also be
provided for testing purposes.  If omitted, they will be generated using
l_getrandom.

ce596058cd eap-wsc: Implement load_settings method
We use the load_settings method to bootstrap the internal state of the

the higher layers, namely:

Global Device parameters
 - Manufacturer
 - Model Name
 - Model Number
 - Serial Number
 - Device Name
 - Primary Device Type
 - OS Version

Session specific parameters
 - MAC Address
 - Configuration Methods
 - RF Bands

The following parameters are auto-generated for each new session, but
can be over-ridden if desired
 - Private Key
 - Enrollee Nonce
