15620721b0 wiphy: Store connected_network on netdev object
Instead of storing the network pointer for each BSS, store it on the
netdev object.  This saves space inside struct bss and makes longer term
refactoring simpler.

67a895c95f wiphy: Simplify code that removes lost networks
The current code is quite complicated and can be made simpler by using
the newly introduced l_hashmap_foreach_remove function.

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.

7b945d948f wiphy: Set the linkmode and operstate of the link
We need to set the linkmode and operstate after successful

Initial value for linkmode is 1 (user space controlled) and
IF_OPER_DORMANT for opermode. After successful authentication,
the operstate is set to IF_OPER_UP.
