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.

9c1780c0a1 wiphy: Use dbus object path as network key in hash 
Modifying a bit how networks are stored inside the hashtable:
1 - instead of the network id, the network's object path is used
2 - network holds the pointer of the object path
3 - the hashtable does not free the key (network_free() will)

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.

we will connect to a certain SSID instead of connecting directly to
a BSS. We pick the best BSS automatically from the BSS list when
connecting to a SSID.
