2bccb7e7dc eapol: Remove user_data from __eapol_rx_packet args 
Instead of passing the user_data parameter in every __eapol_rx_packet
call to be used by EAPOL in all tx_packet calls, add
eapol_sm_set_tx_user_data function that sets the value of user_data for
all subsequent tx_packet calls.  This way tx_packet can be called from
places that are not necessarily inside an __eapol_rx_packet call.

ef9b6f41ce eapol: Separate EAPOL header from struct eapol_key 
This is needed so we can better handle sending and receiving EAPoL
packets other than EAPoL-Key.

830161399e eap: Implement the EAP-TTLS method 
Only EAP as the inner authentication option is supported.  According to
wikipedia this is the most popular EAP-TTLS use case, with MD5 as the
inner EAP's method.

f55db6a1c4 eap: Implement EAP-TLS 
Add the EAP-TLS authentication method.  Currently, all the credentials
data is read from the provisioning file even though things like the
private key passphrase should possibly be obtained from the dbus agent.

00cafb2cc5 wiphy: Check early that a BSS supports compatible ciphers. 
In the D-bus .Connect call return an error immediately if we
find that there's no common cipher supported between iwd, the
network adapter and the AP.  This is to avoid asking the agent
for the passkey if we know the connection will fail.

An alternative would be to only show networks that we can connect
to in the scan results on D-bus but I suspect that would cause
more pain to users debugging their wifi setups on average.

For now, if a passphrase is needed we check once before querying
for passphrase and recheck afterwards when we're about to
associate.

.Connect() call pending so we need to check that netdev->connect_pending
is non-NULL.  It may be a good idea to check this even during initial
handshake.

This permits to optimize on:
1 - one memory allocation used for 2 distinct things
2 - remove the need to re-compute the object path (and the id) when it's
needed, it can use dircetly the one stored in the network structure.

e69b21ccdf wiphy: Don't store rsne unless needed 
Open networks do not contain a RSN element, so storing a 256 byte buffer
was too expensive.

This patch also has the side-effect of fixing detection of Open
Networks.  Prior to this, if the scan results did not contain an RSN IE,
the 'rsne' variable would be set to all zeros.  scan_get_ssid_security
would then be called, but instead of a NULL struct ie_rsn_info, a
non-null, but zerod out ie_rsn_info would be passed in.  This caused the
code to work, but for the wrong reasons.
