The Jenkins master is now known as the controller and the agent it provides is
called "built-in".

The fuzzer needs to take a larger input for the whole disk image to
be most useful. Since the file is small we can test by reading and
writing over the whole file.

vhdx_sync.rs in block_util implements traits to represent the vhdx
crate as a supported block device in the cloud hypervisor. The vhdx
is added to the block device list in device_manager.rs at the vmm
crate so that it can automatically detect a vhdx disk and invoke the
corresponding crate.

Microsoft’s VHDx block device format specification is implemented
here as a crate. This commit includes the implementation for the
fixed and dynamic formats, where the other format is known as
differencing. The vhdx_header.rs, vhdx_bat.rs, vhdx_metadata.rs
implements parser and manipulators for the VHDx header, Block
Allocation Table, and metadata, respectively, for the VHDx file.
The vhdx_io.rs implements read and write routines for the VHDx file.
The vhdx.rs implements the Vhdx structure, which provides the wrapper
functions for standard I/O operations like read, write, and seek.

We are relying on applying empty 'seccomp' filters to support the
'--seccomp false' option, which will be treated as an error with the
updated 'seccompiler' crate. This patch fixes this issue by explicitly
checking whether the 'seccomp' filter is empty before applying the
filter.

The current code was expecting a reply with only the header, which
wasn't reading the rest of payload that was provided. This was causing
the following replies to be completely wrong as they were shifted by the
previous payload that wasn't read.
The simple way to fix this issue is by reading the header and the
expected payload when getting a reply from a DmaUnmap request.

Change the block size to the standard 512 byte sector size to that
disk images can be used (since their partition tables will be specified
in terms of 512 byte sectors.)
Also remove the hugepages=on option from the command line as it is not
necessary.

This commit adds an AArch64-only integration test case called

Based on `--memory-zone` and `--numa` param in the Cloud Hypervisor

It is forbidden that the same memory zone belongs to more than one
NUMA node. This commit adds related validation to the `--numa`

For the purpose of identification, each NUMA node is associated
with a unique token known as a `numa-node-id`. For the purpose of
device tree binding, a `numa-node-id` is a 32-bit integer.
The CPU node is associated with a NUMA node by the presence of a
`numa-node-id` property which contains the node id of the device.

The AArch64 platform provides a NUMA binding for the device tree,
which means on AArch64 platform, the NUMA setup can be extended to
more than the ACPI feature.
Based on above, this commit extends the NUMA setup and data
structures to following scenarios:
- All AArch64 platform
- x86_64 platform with ACPI feature enabled

Instead of panicking with an expect() function, the QcowDiskSync::new
function now propagates the error properly. This ensures the VMM will
not panic, which might be the source of weird errors if only one thread
exits while the VMM continues to run.

We cannot let vhost-user devices connect to the backend when the Block,
Fs or Net object is being created during a restore/migration. The reason
is we can't have two VMs (source and destination) connected to the same
backend at the same time. That's why we must delay the connection with
the vhost-user backend until the restoration is performed.
