Add platform support for IP6GRE and IP6GRETAP tunnels. The former is a
virtual tunnel interface for GRE over IPv6 and the latter is the L2
variant.
The platform code internally reuses and extends the same structure
used by IPv6 tunnels.
Certain platform operations are logged both in nm-platform.c and
nm-linux-platform.c, resulting in duplicate messages. Drop log prints
from the latter.
Add support for a new wireguard link type to the platform code. For now
this only covers querying existing links via genetlink and parsing them
into platform objects.
Devices of different link types can actually have the same MAC address.
We'll want to use this to find a device of a particular type by its
hardware address.
- in wake_on_wlan_restore(), if we decide that there is something
to restore, also clear priv->wowlan_restore by setting it to
IGNORE. That way, we are sure to only try resetting the value
once after setting it.
- from nm_platform_wifi_get_wake_on_wlan(), return IGNORE if
the value cannot be read. If we could not read the value
we should not restore NONE, but don't restore.
Otherwise, we easily get a failure
test:ERROR:src/platform/tests/test-cleanup.c:78:test_cleanup_internal: assertion failed (addresses6->len == 2): (1 == 2)
Avoid that by waiting for kernel to add the link-local
address.
The order we want to enforce is only among addresses with the same
scope, as the kernel always keeps addresses sorted by
scope. Therefore, apply the same sorting to known addresses, so that
we don't try to unnecessary change the order of addresses with
different scopes.

With some manual adjustments on spots that Cocci didn't catch for

Thanks to the marvelous effort of the GNU compiler developer we can now
spare a couple of bits that could be used for more important things,
like this commit message. Standards commitees yet have to catch up.

There are multiple tests with the same in different directories; add a
unique prefix to test names so that it is clear from the output which
one is running.
