Remove the use of 'unwrap()' that assumes the guest address for request
status is always valid, which avoid virtio-block thread panic on
malformed descriptors from the guest.

By checking in the validation logic we get checking for both devices
specified in the initial config but also hotplug too.

There are PCI extended capabilities that can't be passed through the VM
as they would be unusable from a guest perspective. That's why we
introduce a way to patch what is returned to the guest when the PCI
configuration space is accessed. The list of patches is created from the
parsing of the extended capabilities in that case, and particularly
based on the presence of the SRIOV and Resizable BAR capabilities.

The new option parsing for "[..,]" syntax is much stricter and requires
that everything is balanced in terms of brackets. Change the stripping
of the brackets to only strip the first and last one rather than
multiple:
e.g. "[[a,b], [c,d]]" becomes "[a,b],[c,d]" rather than "a,b], [c"

The parsing is now O(1) as we only consider each character in the input
once and further it removes the need for allocating memory for
reassembling the option parameter.

If the BAR for the VFIO device is marked as prefetchable on the
underlying device ensure that the BAR exposed through PciConfiguration
is also marked as prefetchable.

Previously the code used the SmbiosSysInfo structure for that purpose.
Handle 0x0003, DMI type 127, 27 bytes

Wrong DMI structures length: 130 bytes announced, structures occupy 131 bytes.
Fix this by using the correct structure and padding.

There is no need to manually implement Clone for some structures.
It is better to explicitly spell out repr(C) to avoid the compiler

It's been observed on the Bionic image that udev and snapd services can
cause some delay in the VM's shutdown. Disabling them before shutting
down the VM improves the reliability of the test.
Also increasing slightly the sleep time to ensure we give the VM enough
time to shutdown before checking the list of events provided by the
event monitor.

The test virtio_net_latency_us recently failed because of the ethr tool
couldn't complete the latency measurement with the following error
message:
Error dialing the latency connection: dial tcp4
:0-\u003e172.19.0.2:8888: connect: connection refused
The "connection refused" error comes from the Golang Dial function which
couldn't complete as expected because there was no server listening on
the specified port at the specified destination.
In other words, the ethr server wasn't ready when the ethr client tried
to connect to it.
The easy way to avoid this problem is simply by increasing the sleep
time between the command spawning the ethr server in the guest and the
command running the ethr client from the host.

Since it's not possible to run the integration test test_vfio on Azure
at the moment (because of some nested virtualization issues), we can
temporarily run it on the baremetal CI where we already run some VFIO
tests.
