In case the memory size is 0, this means the user defined memory
zones are used as a way to specify how to back the guest memory.
This is the first step in supporting complex use cases where the user
can define exactly which type of memory from the host should back the
memory from the guest.

In anticipation for the need to map part of a file with the function
create_ram_region(), it is extended to accept a file offset as argument.

In case the provided backing file is an actual file and not a directory,
we should not truncate it, as we expect the file to already be the right
size.
This change will be important once we try to map the same file through
multiple memory mappings. We can't let the file be truncated as the
second mapping wouldn't work properly.

Introducing a new CLI option --memory-zone letting the user specify
custom memory zones. When this option is present, the --memory size
must be explicitly set to 0.

It is otherwise seems to be able to cause resource conflicts with
Windows APCI_HAL. The OS might do a better job on assigning resources
to this device, withouth them to be requested explicitly. 0xcf8 and
0xcfc are only what is certainly needed for the PCI device enumeration.

Use of backing file is deprecated hence use the `hugepages` field.
Also use the `boot` field for specifying number of cpus

We may need to store hypervisor speciific data to the VM. This support is
needed for Microsoft hyperv implementations. This patch introduces two
new definitions to Vm trait and implements for KVM.

Problem with the previous solution was that Cleanup stage was not
executed when previous stages failed. We fix this by adding a post
section that executes always after the Aarch64 build completed, no
matter if it has failed, succeeded or been aborted.

"debug!" marco is used in virtio-devices/src/epoll_helper.rs. When"-vvv"
and "--log-file" option was specified, the missing "SYS_write" rule
caused a "bad system call" crash.

Cleanup of the Aarch64 machine can't be done as part of the parallel
stage as this is often skipped. When the build is aborted because
another parallel stage failed, the post actions are simply not
performed. That's why we need a dedicated stage, out of the parallel
ones, to cleanup the Aarch64 machine.

As we never join the spawned virtio-devices worker threads, the error
returned from each worker thread is lost. For now, we simply print out
the error from each worker thread.

This patch adds the seccomp filter list for the virtio_net thread, while
the list was already added for the virtio_net_ctl thread.
Partially fixes: #925
Signed-off-by: Bo Chen <chen.bo@intel.com>
The current seccomp filter for virtio-net is actually for the worker
thread 'virtio_net_ctl' (not the actual worker thread
'virtio_net'). This patch introduces changes to distinguish those two
worker threads and seccomp filters.

We recently added the ability for the gnu and musl workers to retry if
integration test were not passing, relying on some simple Jenkins
options. Unfortunately, this is not working as expected as the retries
never pass either. The suspected reason is the machine itself, which
might be scheduled on some specific hardware, which makes our VMs more
error prone.
Bottom line, on a faulty machine, the tests will always fail, therefore
there is no added value in retrying on the same machine.

Some OS might check for duplicates and bail out, if it can't create a
distinct mapping. According to ACPI 5.0 section 6.1.12, while _UID is
optional, it becomes required when there are multiple devices with the
same _HID.
