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.

4bf109a7ce test: Avoid input() in simple-agent.py. 
That function reads a string of python code and immediately executes
it.  This required passphrases to be input as python literals, we
can just use a string as passphrase instead.

e93dd44607 eapol: Simplify GTK install callback 
Instead of passing in the RSN/WPA elements, simply pass in the
configured cipher.  This will make the implementation of the install_gtk
callback much simpler.

When our own WPA IE or RSN IE are set, extract group and pairwise

Step 4 is always sent without encrypted Key Data according to Section
11.6.6.5.  In the case of WPA, Encrypted Key Data field is reserved, and
should always be 0.  Thus it is safe to drop the !is_wpa condition.

31284bf86b wiphy: If handshake failed check connect_pending 
When handling repeated 4-Way Handshakes from the AP there will be no
.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.
