411888796b packaging: Fix kata-deploy-binaries-in-docker.sh with podman
Instad of bailing out whenever the docker group doesn't exist, just
consider podman is being used, and set the docker_gid to the user's gid.

Also, let's ensure to pass `--privileged` to the container, so
`/run/podman/podman.socket` (which is what `/var/run/docker.sock` points
to) can be passed to the container.

07e76c7392 packaging: Pass RUST_VERSION when building shim-v2
We need to pass the RUST_VERSION, in the same way done for GO_VERSION,
as nowadays both the go and the rust runtime are built.

babd9924c6 virtiofsd: Build inside a container
When moving to building the CI artefacts using the kata-deploy scripts,
we've noticed that the build would fail on any machine where the tarball
wasn't officially provided.

This happens as rust is missing from the 1st layer container.  However,
it's a very common practice to leave the 1st layer container with the
minimum possible dependencies and install whatever is needed for
building a specific component in a 2nd layer container, which virtiofsd
never had.

In this commit we introduce the second layer containers (yes,
comtainers), one for building virtiofsd using musl, and one for building
virtiofsd using glibc.  The reason for taking this approach was to
actually simplify the scripts and avoid building the dependencies
(libseccomp, libcap-ng) using musl libc.

af4f3cdfbd versions: Update TDX QEMU
The previously used repo will be removed by Intel, as done with the one
used for TDX kernel.  The TDX team has already worked on providing the
patches that were hosted atop of the QEMU commit with the following hash
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0 as a tarball in the
https://github.com/intel/tdx-tools repo, see
https://github.com/intel/tdx-tools/pull/162.

On the Kata Containers side, in order to simplify the process and to
avoid adding hundreds of patches to our repo, we've revived the
https://github.com/kata-containers/qemu repo, and created a branch and a
tag with those hundreds of patches atop of the QEMU commit hash
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0.  The branch is called
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0-plus-TDX-v3.1 and the tag is
called TDX-v3.1.

Knowing the whole background, let's switch the repo we're getting the
TDX QEMU from.

bfc3c45854 versions: Update TDX kernel
The previously used repo has been removed by Intel.  As this happened,
the TDX team worked on providing the patches that were hosted atop of
the v5.15 kernel as a tarball present in the
https://github.com/intel/tdx-tools repos, see
https://github.com/intel/tdx-tools/pull/161.

On the Kata Containers side, in order to simplify the process and to
avoid adding ~1400 kernel patches to our repo, we've revived the
https://github.com/kata-containers/linux repo, and created a branch and
a tag with those ~1400 patches atop of the v5.15.  The branch is called
v5.15-plus-TDX, and the tag is called 5.15-plus-TDX (in order to avoid
having to change how the kernel builder script deals with versioning).

Knowing the whole background, let's switch the repo we're getting the
TDX kernel from.

cde438ceb7 image_rpc: always call verify_cid after determining the cid
Prior to this patch, we were missing a call to `verify_cid` when the cid
was derived from the image path, which meant that the host could specify
something like "prefix/..", and we would use ".." as the cid. Paths
derived from this (e.g., `bundle_path`) would not be at the intended
tree.

This patch factors the code out of `pull_image` so that it can be more
easily tested. Tests are added for a number of cases.

53f209af44 libs/kata-types: adjust default_vcpus correctly
With default_maxvcpus = 0 and default_vcpus = 1 settings, the
default_vcpus will be set to 0 and leads to starting fail.

The default_maxvcpus is not set correctly when it is set to 0,
and the default_vcpus is set to 0.

The correct action is setting default_maxvcpus to the max number
of CPUs or MAX_DRAGONBALL_VCPUS, and the default_vcpus should be
set to the desired value if the valuse is between 0 and
default_maxvcpus.

f476470c37 packaging: Mount $HOME/.docker in the 1st layer container
In order to ensure that the proxy configuration is passed to the 2nd
layer container, let's ensure the $HOME/.docker/config.json file is
exposed inside the 1st layer container.

For some reason which I still don't fully understand exporting
https_proxy / http_proxy / no_proxy was not enough to get those
variables exported to the 2nd layer container.

In this commit we're creating a "$HOME/.docker" directory, and removing
it after the build, in case it doesn't exist yet.  The reason we do this
is to avoid docker not running in case "$HOME/.docker" doesn't exist.

This was not tested with podman, but if there's an issue with podman,
the issue was already there beforehand and should be treated as a
different problem than the one addressed in this commit.

fe61070426 versions: Upgrade to Cloud Hypervisor v27.0
This release has been tracked in our new [roadmap project ](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration v27.0.

**Community Engagement**
A new mailing list has been created to support broader community discussions.
Please consider [subscribing](https://lists.cloudhypervisor.org/g/dev/); an announcement of a regular meeting will be
announced via this list shortly.

**Prebuilt Packages**
Prebuilt packages are now available. Please see this [document](https://github.com/cloud-hypervisor/obs-packaging/blob/main/README.md)
on how to install. These packages also include packages for the different
firmware options available.

**Network Device MTU Exposed to Guest**
The MTU for the TAP device associated with a virtio-net device is now exposed
to the guest. If the user provides a MTU with --net mtu=.. then that MTU is
applied to created TAP interfaces. This functionality is also exposed for
vhost-user-net devices including those created with the reference backend.

**Boot Tracing**
Support for generating a trace report for the boot time has been added
including a script for generating an SVG from that trace.

**Simplified Build Feature Flags**
The set of feature flags, for e.g. experimental features, have been simplified:

* msvh and kvm features provide support for those specific hypervisors
(with kvm enabled by default),
* tdx provides support for Intel TDX; and although there is no MSHV support
now it is now possible to compile with the mshv feature,
* tracing adds support for boot tracing,
* guest_debug now covers both support for gdbing a guest (formerly gdb
feature) and dumping guest memory.

The following feature flags were removed as the functionality was enabled by
default: amx, fwdebug, cmos and common.

**Asynchronous Kernel Loading**
AArch64 has gained support for loading the guest kernel asynchronously like
x86-64.

**GDB Support for AArch64**
GDB stub support (accessed through --gdb under guest_debug feature) is now
available on AArch64 as well as as x86-64.

**Notable Bug Fixes**
* This version incorporates a version of virtio-queue that addresses an issue
where a rogue guest can potentially DoS the VMM,
* Improvements around PTY handling for virtio-console and serial devices,
* Improved error handling in virtio devices.

**Deprecations**
Deprecated features will be removed in a subsequent release and users should
plan to use alternatives.

* Booting legacy firmware (compiled without a PVH header) has been deprecated.
All the firmware options (Cloud Hypervisor OVMF and Rust Hypervisor Firmware)
support booting with PVH so support for loading firmware in a legacy mode is no
longer needed. This functionality will be removed in the next release.

Details can be found: https://github.com/cloud-hypervisor/cloud-hypervisor/releases/tag/v27.0

Note: To have the new API of loading firmware for booting (e.g. boot
from td-shim), a specific commit revision after the v27.0 release is
used as the Cloud Hypervisor version from the 'versions.yaml'.

17de94e118 microvm: Remove kernel_irqchip=on option
`kernel_irqchip` option doesn't seem to bring any benefits and, on the
contrary, its usage cause issues when using the microvm machine type.

With this in mind, let's remove it.

Fixes: #1984, #4386
