sysext: introduce ARCHITECTURE field to match host architecture
When an extension image has binaries they should match the host
architecture. Currently there is no way to specify this requirement.
Introduce an ARCHITECTURE field in the extension's release file that
may be set to prevent loading on the wrong host architecture.
Since this new field is introduced late, we don't want to make
specifying it mandatory as it would break existing sysext images.

sysext: support distribution-independent extensions using ID=_any
A sysext image that merely contains static binaries has no dependency
on the host distribution and should be able to be used anywhere.

dhcp6: gracefully handle NoBinding error
When we receive NoBinding status code, the requesting binding (address or

hwdb: Apply existing accel orientation quirk to all Chromebooks
The cros-ec-accel and cros-ec-accel-legacy kernel modules internally
correct for the board-specific accelerometer mounting orientations.
Their sensor outputs are in a standard reference frame consistent across
different boards, so the orientation matrix already added for a number
of devices should apply to every device using cros-ec accelerometers.
The different matrix for the 'Nocturne' board seems to be an error.
Replace the existing hwdb rules for select Chromebooks with generic
rules that apply to all Chromebooks.

sd-device: allow to create sd-device object through a symlink outside of /sys
For example, /proc/device-tree is a symlink to /sys/firmware/devicetree/base,
and the kernel documentation says the symlink should be used by userspace app.
See, https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw.
Hence, it is useful to make `sd_device_new_from_path()` support such symlink.

udev: net_id: Use devicetree aliases when available
Devicetree firmware contains an "aliases" node, containing various
aliases for devices described by the firmware. For ethernet devices,
these are named "ethernet0", "ethernet1", etc. They provide a convenient
means of numbering ethernet devices, especially on systems with no other
stable number other than the address. In particular, U-Boot already uses
these aliases to name its ethernet devices.
Previously, there have been attempts (such as [1]) to add support for
these aliases to Linux. However, these patches have been rejected
because it is the maintainers' view that naming policy be left to
userspace. Well, systemd is userspace, so here we are.
In terms of implementation, apparently there can be multiple device
trees at once. I have decided to dodge this problem for now, and just
use /proc/device-tree. If it is desired to support multiple device trees
later, then the scheme can be modified to include the device tree's
index. For example, /sys/firmware/devicetree/base2/aliases/ethernet3
might be named enb2d3.
For the moment we only support "ethernetX" aliases. Future patches might
want to also handle "canX" and "wifiX".
It is common on boards with only one ethernet device to use an alias of
just "ethernet". In this case, the index is an implicit 0. In case the
author of the firmware made a mistake, we check to ensure that aliases
of "ethernet" and "ethernet0" do not both exist.

resolvctl: only remove protocol after last dot when mangling ifname for resolvconf
ifname_resolvconf_mangle is supposed to remove protocol suffixes like .dhcp
from interface names. But this removed also valid parts of the ifname like

After this change, everything behind the last dot is removed instead of the first.
