Using fsopen()/fsconfig(), we can check if hidepid/subset are supported to
avoid the noisy logs from the kernel if they aren't supported. This works
on centos/redhat 8 as well since they've backported fsopen()/fsconfig().
Instead of succeeding when either the firmware reports a TPM device
or we find a TPM device, let's check that the firmware reports a TPM
device and the TPM subsystem is enabled in the kernel.
To check whether the subsystem enabled, we check if the relevant
subdirectory in /sys exists at all.
Previously, interfaces are partially reconfigured in a spurious way.
Let's use the same way as `networkctl reconfigure`.
Hopefully fixes#14987 and #24997.
The script has a shebang and .sh extension, so make it executable

Repart is growing into an important tool on its own, and users might
want to install newer versions on systems that have older systemd. Let's
make this easier by providing a standalone binary.

On various ARM systems, it is possible to find devices on AMBA bus.
This is defined in Linux kernel drivers/amba/bus.c as separate bus
type. Udev currently does not recognize this when building ID_PATH
which leads to ID_PATH containing the suffix from next recognized
parent device. On ST STM32MP15xx with SDIO WiFi, the ID_PATH looks
like 'platform-soc', which is not unique and basically useless. On
NXP i.MX8M Plus with SDIO WiFi, ID_PATH is 'platform-30b40000.mmc'
which is far more useful.
Add the 'amba' subsystem handling the same way 'platform' subsystem
is handled to get ID_PATH 'platform-soc-amba-48004000.sdmmc' on the
former, which is far more useful compared to 'platform-soc'.

$ udevadm info --attribute-walk --path=/devices/platform/soc/48004000.mmc/mmc_host/mmc1/mmc1:0001/mmc1:0001:1/net/wlan0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

To support predictable interface names in various embeeded systems
add support for an additional naming scheming using the USB host
interface. Several asics have usb controllers that are platform
devices and not children of a pci interface. These embedded systems
should be able to enumerate interfaces by udev path as well to support
configurations and policies.
