Instead of truncating the device name when it exceeds IFNAMSIZ length;
let device_set_ifname return an error code and do not add the device
to the device list.
This avoids possible issues with device names becoming identical due the
truncation and as a result unexpected behavior.
Further let the different device types gracefully handle the error code
returned by device_init

As device name is used as key in avl list a device name change will break the avl find logic.
Function device_set_ifname offers api to set the device name and re-inserts the avl node in the list
when the avl key value is changed.

Set link_state for all device types via the device_set_link API as all devices are registered
in the device tree list making it possible to always get the device via device_get.
The decice link state parameter will now actually reflect the corresponding kernel device
carrier state in all cases.
Before this change a vlan/macvlan device could still have link_state enabled if an interface
was brought down; this was the case when the parent vlan/macvlan device was still enabled as
the netlink link_state event would be dropped for vlan/macvlan devices due to keep_link_state
in the function cb_rtnl_event.

Just like other device types old vlan style devices are added to
the device list which means they're displayed when the device list
is displayed via ubus.
Additionally global device setting config like default packet
steering behavior is now also applied for old style vlan devices
when doing a network reload.

Introduce a new device event "topology change" that gets signaled
by bridges on adding/removing members.
On "topology changes" the proto handlers are requested to "renew"
which is most useful for DHCP.

The link layer state is monitored for a given interface; an interface will be setup
when both enabled and link layer active. Likewise an interface will be teared down
when either disabled or link layer down.

Set the device name earlier so that the logging done inside of
'device_init_virtual' can print the name of the device being
initialized (instead of an empty string).
