Hard-coded Qemu machine options create challenges when running Kata
with latest Qemu (v5.0) or with latest processor version.
This patch makes it configurable by leveraging the existing machine_accelerators
option in configuration.toml.

The default ppc64le Qemu binary path was specific for Ubuntu.

qemu_ppc64le.go applies the "tsc=reliable", "no_timer_check" and
"noreplace-smp" kernel parameters, despite those being x86 specific. So,
just remove them.

Let's add information on how to debug shimv2 when using cri-o, similarly

Dup a new file descriptor for temporary logger writer,
since this logger would be dropped and it's writer would
be closed out of if definition scope, which would cause
the logger process thread terminated if it used the original
pipe write fd.

With this change, a container is not longer given access to
the underlying root partition.
This is done by explicitly adding the root partition
to the device cgroup of the container.

Improve the output of the data collection script to use lots more folds.
This makes it easier to review the information when viewing the pasted

Add `start_section()` and `end_section()` functions to the data

Redefine `show_header()` and `show_footer()` to use the new functions.

Now that the Kata containerd shim v2 can display a version string,

All components should support a `--version` option to allow clear
identification of the version of the component being used.
Note that the build changes are required to allow the shim binary to
access the golang code generated by the build (such as the `version`
variable).
Fixes: #307.

Add a new system component, used only when tracing is enabled. The
component listens to the agent over VSOCK, forwarding trace spans
created by the agent in the virtual machine onwards to an OpenTelemetry
collector (such as Jaeger) running on the host.

The agent logger is useful and generic enough that it can be used by
other components, so move the agent logging package to below a top level
`pkg` to encourage re-use.

Clean up all clippy warning.
Also fix a bug in dealing with IFLA_IFNAME attribute.
nlh.addattr_var(IFLA_IFNAME, name.as_ptr() as *const u8, name.len() + 1);
The `name` is a rust String, which doesn't including the trailing '\0',
so name.len() + 1 may cause invalid memory access.

Implment `TryFrom<IPAddress> for RtIPAddr` instead of From<IPAddress>,
so error code could be returned instead of unwrap().
Do the same for `TryFrom<Route> for RtRoute`.

There are too much unsafe code in the netlink crate, we need to reduce
unsafe code as much as possible. To achieve this, methods are classified
as public interfaces and internal methods.
All public interface of RtnlHandle has been reimplemented as safe code,
only some public helper functions to manipulater Netlink message data
structures are implemented as unsafe code.
The code to parse IPv4/IPv6/MAC addresses has been moved to a dedicated
file named parser.rs.

The netlink crate is a library to communicate with Linux kenrel by using
the netlink socket. It's generic enough to be reused by other clients.
So get rid of dependency on the rustjail crate by:
1) normalize all pub interfaces to return Result<T, nix::Error>,
2) add helpers to reduce duplicated code,
3) move parse_mac() into lib.rs,
