The old API remains usable, and will remain usable for two releases but
we should only advertise the new API.

Introduce a new top level member of VmConfig called PayloadConfig that
(currently) encompasses the kernel, commandline and initramfs for the
guest to use.
In future this can be extended for firmware use. The existing
"--kernel", "--cmdline" and "initramfs" CLI parameters now fill the
PayloadConfig.
Any config supplied which uses the now deprecated config members have
those members mapped to the new version with a warning.

Whenever starting a test with the capture_output option, both stdout and
stderr pipes are resized to a greater capacity. But the problem is that
when the system call fcntl() fails, we need to know about the error
returned by the system so that we can apply the necessary changes.
This patch simply enhances the error checking and reporting related to
the invocation of fcntl() when trying to resize a pipe.

The test test_virtio_block_topology has been recently failing due to an
error happening in losetup while trying to set the block size. Since
there's no option in losetup for retrying, we took the approach of
programming the expected behavior of creating a loop device relying
directly on the system ioctl LOOP_CONFIGURE. We apply a retry loop based
on the result returned by this ioctl, so that we don't fail on the first
try. We also added a sleep before retrying, hoping this would help the
next iteration to succeed.

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.

is also marked as prefetchable.

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.
