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.

9992d3aeda eapol: Extract & keep track of desired ciphers
When our own WPA IE or RSN IE are set, extract group and pairwise
ciphers.  These ciphers are the ones we desire to use for the secure
connection.

2ba7867e9f eapol: Drop unneded check in verify_ptk_4_of_4
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.

Legacy WPA will be used with APs that advertise WPA support and

93aaf21459 wiphy: Add initial preference management
This patch saves off the PSK generated based on the passphrase provided
by the agent/user.  The PSK is saved only if the connection is
successful.

Subsequent connection attempts to the known AP use the PSK saved on the
filesystem (default /var/lib/iwd/<ssid>.psk).  If the connection fails,
the agent will again be asked for the passphrase on the next attempt.

6921e239a4 wiphy: Only support UTF-8 SSIDs
We will ignore non-UTF8 based SSIDs.  Support for non-UTF8 SSIDs seems
to be of dubious value in the real world as the vast majority of
consumer devices would not even allow such SSIDs to be configured or
used.

There also seems to be no compelling argument to support such SSIDs, so
until that argument arrives, non-UTF8 SSIDs will be filtered out.  This
makes the D-Bus API and implementation much easier.
