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.

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.

Rather than using a credible TestBlock to capture the test assertions
instead use a catch_unwind block to catch the panic and turn
it into a Result<>.
If block panicked or the child binary had non-zero exit then, and only
then, print out the child output.
This results in a clearer test output with no interleaving.
Currently only test_counters is ported to this methodology to
demonstrate its use.

`cargo test` runs every test in its own process and by default will
collect the output from the test and only print it if the test fails.
`--nocapture` instead prints any output from the test immediately and
does not collate it - this leads to interleaving.
`--nocapture` might be useful for local test debugging but is not
something that is helpful, and is instead unhelpful for our CI as a
whole.

Based on the way KVM_GET_MSRS and KVM_SET_MSRS work, both function are
very unlikely to fail, as they simply stop looping through the list of
MSRs as soon as getting or setting one fails. This is causing some
issues with the snapshot/restore feature, as on some platforms, we only
save a subset of the list of MSRs, leading to unproper way of saving the
VM.
The way to address this issue is by checking the number of MSRs get/set
matches the expected amount from the list. In case it does not match, we
simply ignore the failing MSR and continue getting/setting the rest of
the list. By doing this by iterations, we end up getting/setting as many
MSRs as the platform can support.
