Adjust the release workflow to move the conditional check on the tag
creation into the steps that create the release/upload the assets.
This allows us to ensure we're always in a releaseable state.

From Rust 1.59, the cargo command is now able to strip a binary [1].
This can be enabled in Cargo.toml by adding a `strip = "true"` to
the `[profile.release]` section.
Adding such binary stripping support in Cargo.toml of the project,
also change the stripping process in the release workflow to the one
using toolchain, so that the AArch64 release binaries can also
be stripped.

The code of the stable branch diverges from the main branch, so we
can't directly backport the corresponding commit to fix the clippy

This change is important to do a proper resource cleanup. We decided
to do this repetitive approach as VirtioCommon can't implement Drop
without major changes to the corresponding code. Also, devices such as
Net can't easily use the epoll_threads-abstraction from VirtioCommon as
it has multiple threads with different semantics.

The number of entries in the refcount table was incorrectly calculated
given there was no need for dividing the number of refblock clusters.
The number of refblock clusters is the number of entries in the refcount
table.

This integer overflow was triggered with fuzzing on the virtio-net
device. The integer overflow is from the wrong assumption that the
packets read from or written to the tap device is always larger than the
size of a virtio-net header.

This panic was triggered with fuzzing on the virtio-net device. This
commits handles the error explicitly to avoid the panic, which also
makes the fuzzer happy (as panic is treated as bugs).

If the KVM version is too old (pre Linux 5.7) then fetch the CPUID
information from the host and use that in the guest. We prefer the KVM
version over the host version as that would use the CPUID for the
running CPU vs the CPU that runs this code which might be different due
to a hybrid topology.

There is no need for this test any longer as we have plenty of other

Further this test used unmodified bionic image, which not only will be
EOLed soon but also took a long time to shutdown as it still had snapd
installed.

It is required to close all file descriptors pointing to an opened TAP
device prior to reopening the TAP device; otherwise it will return
-EBUSY as the device can only be opened once (excluding MQ use cases.)
When rebooting the VM the virtio-net threads would still be running and
so the TAP file descriptor may not have been closed. To ensure that the
TAP FD is closed wait for all the epoll threads to exit after receiving the
KILL_EVENT.
