As we never join the spawned virtio-devices worker threads, the error
returned from each worker thread is lost. For now, we simply print out
the error from each worker thread.

From the experiments of running integration tests on my local machine,
auditd occationally reported the 'brk' syscall is needed for the
'virtio-rng' worker thread.

This patch adds the seccomp filter list for the virtio_net thread, while
the list was already added for the virtio_net_ctl thread.
Partially fixes: #925

The current seccomp filter for virtio-net is actually for the worker
thread 'virtio_net_ctl' (not the actual worker thread
'virtio_net'). This patch introduces changes to distinguish those two
worker threads and seccomp filters.

We recently added the ability for the gnu and musl workers to retry if
integration test were not passing, relying on some simple Jenkins
options. Unfortunately, this is not working as expected as the retries
never pass either. The suspected reason is the machine itself, which
might be scheduled on some specific hardware, which makes our VMs more
error prone.
Bottom line, on a faulty machine, the tests will always fail, therefore
there is no added value in retrying on the same machine.

Some OS might check for duplicates and bail out, if it can't create a
distinct mapping. According to ACPI 5.0 section 6.1.12, while _UID is
optional, it becomes required when there are multiple devices with the
same _HID.

Using the Rust Barrier mechanism, this patch forces each virtio device
to acknowledge they've been correctly paused before going further.

If the build was aborted then the dev_cli.sh code that is responsible
for changing the file ownership will not get run. This results in the
failure to delete some of the files in the workspace.

Now the testing aspects are run inside a panic handler block rather than
inside a credibility TestBlock. If the test fails then the output from

Instead of passing only the event type through the handle_event()
callback, we make the trait slightly more generic by providing the
epoll event to each virtio device implementation.
This is particularly useful for vsock as it will need the event set.

The brk syscall is not always called as the system might not need it.
But when it's needed from the API thread, this causes the thread to
terminate as it is not part of the authorized list of syscalls.
This should fix some sporadic failures on the CI with the musl build.

Even if the vhost-user-net device did implement all currently-defined
features, it would be very short-sighted to use ::all(), because if a
new feature was defined later, the device would start claiming to
implement it even though it didn't.
More practically, claiming to implement all features breaks using QEMU
with the cloud-hypervisor vhost-user-net backend, because QEMU will
negotiate VHOST_USER_PROTOCOL_F_SLAVE_REQ, and then break when the
communication channel isn't actually set up.
I wasn't sure exactly which features the backend should claim to
implement, though. Definitely MQ, and I'm fairly certain none of the
features I've ommitted are implemented. But I'm not sure about
REPLY_ACK. As far as I can tell it should be implemented entirely by
the vhost crate, with no cooperation required from the vhost-user-net
backend itself, so there should be no reason to let a frontend use it
if it wants to. But despite this, neither vhost-user-fs nor
vhost-user-blk claims to implement it.
