German Maglione, one of the current virtio-fs developers, has brought to
our attention that using "announce-submounts" could help us to prevent
inode number collisions.
This feature was introduced a year ago or so by Hanna Reitz as part of
the 08dce386e77eb9ab044cb118e5391dc9ae11c5a8, and as we already mandate
QEMU >= 6.1.0, let's take advantage of that.

When building with `ARCH=x86_64`, the previous `Makefile` will use it
without checking and cause:
Makefile:319: *** "ERROR: No hypervisors known for architecture x86_64 (looked for: acrn firecracker qemu cloud-hypervisor)". Stop.
This commit fix the above issue by checking `ARCH` no matter where it
is assigned.

to cover a Red Hat (adjacent) rootfs with great cross-platform compatibility
and a workable release cadence. The previous CentOS & Fedora workflows are
simplified.
Also remove unnecessary `/usr/share` files as on Ubuntu and mark Alpine
as unuspported on ppc64le (due to musl, for a while already).

We install Rust in the build containers, but we also install Rust in
`rootfs.sh` if it is missing. It makes sense to install Rust in the build
containers so it does not have to be installed every time, but for that check
to work on non-login shells, we should source `.cargo/env` before running it.

Change the variables `mountTypeFieldIdx := 8`, `mntDestIdx := 4` and `netNsMountType := "nsfs"` to const.
And unify the variable naming style, modify `mntDestIdx` to `mountDestIdx`.

Add support for building TDX kernel from github.com/intel/tdx
To build a guest kernel that supports Intel TDx run:
```
./build-kernel.sh -s -x tdx -d setup
./build-kernel.sh -s -x tdx -d install
```

Pulling image is the most time-consuming step in the container lifecycle. This PR
introduse nydus to kata container, it can lazily pull image when container start. So it
can speed up kata container create and start.

In commit 78dff468bf1 we introduced logic to rewrite PCIDEVICE_ environment
variables for the container so that they contain correct addresses for the
Kata VM rather than for the host. Unfortunately, we never actually invoked
the function to do this.
It turns out we need to do this not only at container creation time, but
also for environment variables supplied to processes exec-ed into the
container after creation (e.g. with crictl exec). Add calls to make both
those updates.

add_devices() generates a mapping of host to guest PCI addresses which is
used to update some environment variables for the workload. Currently it
just does this locally, but it turns out we're going to need the same map
again in order to correct environment variables for processes exec-ed into
the existing container.
Move the map to the sandbox structure so we can keep it around for those
later uses.

This function updates PCIDEVICE_ environment variables (such as those
supplied by the Kubernetes SR-IOV plugin) in the OCI spec to be correct
for the Kata VM, rather than for the host.
We neglected to actually call this function, however, and it turns out that
when we do, we need to do things slightly different. We actually need to
adjust envionment variables both in the OCI spec when creating a container
and also in the variables supplied for exec-ing a new process within an
existing container.
Adjust the function so that it can be used for both these cases.

We don't need to call NewNetwork() twice, and we can have the VM factory
case return immediatly. That makes the code more readable.

We are converting the Network structure into an interface, so that
different host OSes can have different networking implementations for
Kata.
One step into that direction is to rename all the Network structure
fields and methods to something that is less Linux networking namespace
specific. This will make the Network interface naming consistent.

We are replacing the NetworkingNamespace structure with the Network

Endpoints creations, attachement and hotplug are bound to the networking
namespace described through the Network structure.
Making them Network methods is natural and simplifies the code.

For simplicity sake, there should only be one networking structure per
sandbox, as opposed to two (Network and NetworkingNamespace) currently.
This commit start expanding the Network structure in order to eventually
make it the single representation of a virtcontainers sandbox
