Add input for -pidfile option of qemu, so that we can get pid of
qemu main process, and apply resource limitations to it.

This patch fixes the wrong behavior of specifying a netdev, MAC
address or PCI address entry when those were empty. Instead, it
does not provide those entries if the content is empty.

Any device inheriting from virtio-pci can specify a ROM file. This
option is provisioned by default with "efi-virtio.rom", but most
of the time, firmwares such as OVMF or seabios will already support
what is provided by this ROM file.
In order to reduce the "forced" dependency on such ROM file, govmm
should provide an empty path if the consumer of the library does not
provide one.
This patch reorganizes the list of devices, so that it gets easier to
list which devices inherit from virtio-pci, and then adds the romfile
option to every single device that support this option.

In case the type of bridge is PCIEBridge, which we expect as ending
up using pcie-pci-bridge device from Qemu, the properties chassis_nr
and shpc don't exist.
This commit simply fixes this use case by removing those parameters
from the command line.

The memory-backend-ram should also be set to a numa node instead of
being inserted as a new device. Otherwise it becomes additional memory
and requires explicit online to be available, instead of just being a
backend of the memory specified by -m option.

In addition to supporting hotplug for VFIO mediated device on PCI bridge,
this patch adds hotplug functionality on root bus.
When parameter bus and addr are set to be empty, the system will pick up
an empty slot on root bus.

The contents of .iso used to bootstrap VMs with cloudinit are
initialised using a precreated, short-lived directory. The
permissions on this directory were too lenient. This commit
restricts access to this directory to the user and his/her group.

govmm has ExecuteBlockdevAdd() function and ExecuteBlockdevDel() function
doesn't compatible with qemu 2.8,because blockdev-add and x-blockdev-del usages
are different between qemu 2.7 and qemu 2.8
Follow the qemu 2.7 and qemu 2.8 qmp-commands.txt documents to modify ExecuteBlockdevAdd()
function and ExecuteBlockdevDel() function to be compatible with qemu 2.8

If we hotplug a nic with args mq=on, its qdisc will be mq by default.
This aligns with cold plug nics.

With qemu 2.10, a write lock was added for qcow images that
prevents the same image to be passed more than once.
This can be over-ridden using the --share-rw option which is
desired for raw images.
This solves an issue with running Kata with devicemapper
using the privileged mode as in this case all devices on the host
are passed to the container using the block device associated
with the rootfs, causing it to be passed twice to qemu.

For machines types based on PCIe like q35, device addr and bus must be specified.
For machines types based on PCI like pc, device addr must be specified and bus
is optional since devices can be hot plugged directly on the root bus.
