e70eca9b48 network: enable DHCP broadcast flag if required by interface
Some interfaces require that the DHCPOFFER message is sent via broadcast
if they can't receive unicast messages before they've been configured
with an IP address.

E.g., s390 ccwgroup network interfaces operating in layer3 mode face
this limitation. This can prevent the interfaces from receiving an
IP address via DHCP, if the have been configured for layer3.

To allow DHCP over such interfaces, we're introducing a new device
property ID_NET_DHCP_BROADCAST which can be set for those.
The networkd DHCP client will check whether this property is set
for an interface, and if so will set the broadcast flag, unless
the network configuration for the interface has an explicit
RequestBroadcast setting.

Besides that, we're adding a udev rule to set this device property
for ccwgroup devices operating in layer3 mode, which is the case
if the ID_NET_DRIVER property is qeth_l3.

Supercedes #18829

4dd465cb4e udev: Extract RAM properties from DMI information
Add memory_id program to set properties about the physical memory
devices in the system. This is useful on machines with removable memory
modules to show how the machine can be upgraded, and on all devices to
detect the actual RAM size, without relying on the OS accessible amount.

Closes: #16651

88936ed6f9 rules: remove 61-autosuspend-manual.rules
It doesn't hurt, but there's no point in keeping it now. Any changes
can be added to 60-autosuspend.hwdb.

79dc5d35dd tools: rewrite make-autosuspend-rules.py and add udev rules
Concatenating strings is not a very efficient approach. And in this case fully
unnecessary. We also need some rules to make use of those hwdb entries.

PCI needs to be 8 characters, not 4. And we need to use uppercase hexadecimal
for both. With udev rules this made no difference, but hwdb match is case
sensitive.

Fixes #16119.

ef2ad30aee Rename udev's rules/ to rules.d/
This change is only about the source tree. We have tmpfiles.d/, modprobe.d/,
sysctl.d/, and sysusers.d/, but for historical reasons, rules/ didn't fit this
pattern. We also *install* it as rules.d/. Let's rename to be consistent.
