When link goes !IFF_UP by internal or external action, we need to delete
related routes from the route cache. The same is done for both addresses
and routes upon link removal.

Bluetooth device hardware addresses won't change during the lifetime
of the object (since that would mean a completely new device) and
they also won't have an ifindex because they aren't netdevices.
Various bits of the core periodically call nm_device_update_hw_address()
to update a device's hardware address, but this function expects that
any device with a hardware address also has an ifindex. Except that
Bluetooth devices don't because they aren't netdevices.
Modify the get_hw_address_length() function to return a boolean
indicating whether or not the address can ever change, and set that
for BT devices. nm_device_update_hw_address() then exits early if
there's no point in re-checking the hardware address, avoiding the
assertion.

The previous ignore-carrier rules did not work well with dynamic IP
(dhcp/slaac) connections. Change the rule so that only static IP
connections can be activated when carrier is not present (but both
static and dynamic connections will remain up when carrier is lost).
Abstract class, fake implementation and a manual testing tool for
NetworkManager's internal IPv6 router discovery module. When a real
implementation is ready, it will replace nm-ip6-manager and will be used
by nm-device.
Callers of these functions now only care whether two IP configs are
different and not what specific property changed, so we can simplify
this code down to a simple comparison for equality, based on the hashing
that's already done for the DNS manager.
Note that this patch doesn't effectively change any code.
Functions moved from nm-system:
* nm_system_apply_ip?_config → nm_ip?_config_commit
* ip?_dest_in_same_subnet → nm_ip?_config_destination_is_direct
Functions moved from NetworkManagerUtils:
* nm_utils_merge_ip?_config → nm_ip?_config_merge_setting
Functions renamed (and moved down to form one group):
* nm_ip?_config_new_for_interface → nm_ip?_config_capture
(The rationale for the rename is that from the achitectural point of
view it doesn't matter whether the function creates a new object or
updates an existing one. After the rename, it's obvious that
nm_ip?_config_capture() and nm_ip?_config_commit() are counterparts of
each other.)
0652d9c596 changed IP states like this:
| old behaviour | new behaviour
---------------------------------------------------------
success | IP_DONE && config is not NULL | IP_DONE
failure | IP_DONE && config is NULL | IP_FAIL
But some failure paths was not updated.
nm_platform_*_sync() functions check the cached kernel configuration
items (addresses, routes) before adding addresses to the kernel.
Therefore we don't need to be so careful about pushing NetworkManager
configuration to the kernel.
This patch helps to avoid having to compare nm_ip[46]_config objects,
which should only be created when a configuration change is being
performed.
in nm_device_start_ip_check(), because it is called from the state handler
(nm_device_state_changed()).
