We have to resort to a bit of a hack: python-libevdev gets the
properties from libevdev at module init time. If libevdev hasn't been
rebuilt with the new property it won't be automatically populated. So we
hack around this by constructing the property manually.

- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.

This commit is a rewrite almost from scratch of vmtest.sh.
By relying on virtme-ng, we get rid of boot2container, reducing the
total bootup time (and network requirements). That means that we are
relying on the programs being installed on the host, but that shouldn't
be an issue. The generation of the kconfig is also now handled by
virtme-ng, so that's one less thing to worry.
I used tools/testing/selftests/vsock/vmtest.sh as a base and modified it
to look mostly like my previous script:
- removed the custom ssh handling
- make use of vng for compiling, which allows to bring remote
compilation (and potentially remote compilation on a remote container)
- change the verbosity logic by having 2 levels:
- first one shows the tests outputs
- second level also shows the VM logs
- instead of only running the compiled kernel when it is built, if we
are in the kernel tree, use the kernel artifacts there (and complain
if they are not built)
- adapted the tests list to match the HID subsystem tests

Some specified options rely on NETFILTER_XTABLES_LEGACY to be enabled.
IP_NF_TARGET_TTL for instance depends on IP_NF_MANGLE which in turn
depends on IP_NF_IPTABLES_LEGACY -> NETFILTER_XTABLES_LEGACY.
Enable relevant iptables config options explicitly, this is needed
to avoid breakage when symbols related to iptables-legacy
will depend on NETFILTER_LEGACY resp. IP_TABLES_LEGACY.
This also means that the classic tables (Kernel modules) will
not be enabled by default, so enable them too.

hid-tools 0.10 fixes one inconvenience introduced by
commit 6a9e76f75c ("HID: multitouch: Disable touchpad
on firmware level while not in use")
This change added a new callback when a hid-nultitouch device is opened
or closed to put the underlying device into a given operating mode.
However, in the test cases, that means that while the single threaded
test is run, it opens the device but has to react to the device while
the open() is still running. hid-tools now implements a minimal thread
to circumvent this.
This makes the HID kernel tests in sync with hid-tools 0.10.
This has the net effect of running the full HID python testsuite in 6
minutes instead of 1 hour.
