ad45c52fbe runtime/device: Record guest PCI path for VFIO devices
For several device types which correspond to a PCI device in the guest
we record the device's PCI path in the guest.  We don't currently do
that for VFIO devices, but we're going to need to for better handling
of SR-IOV devices.

To accomplish this, we have to determine the guest PCI path from the
information the VMM gives us:

For qemu, we query the slot of the device and its bridge from QMP.

For cloud-hypervisor, the device add interface gives us a guest PCI
address.  In fact this represents a design error in the clh API -
there's no way it can really know the guest PCI address in general.
It works in this case, because clh doesn't use PCI bridges, so the
device will always be on the root bus.  Based on that, the PCI path is
simply the device's slot number.

243d4b8689 runtime: Sandbox: Add addSwap and removeSwap
addSwap will create a swap file, hotplug it to hypervisor as a special
block device and let agent to setup it in the guest kernel.
removeSwap will remove the swap file.

Just QEMU support addSwap.

6b0dc60dda runtime: Fix ordering of trace spans
A significant number of trace calls did not use a parent context that
would create proper span ordering in trace output. Add local context to
functions for use in trace calls to facilitate proper span ordering.
Additionally, change whether trace function returns context in some
functions in virtcontainers and use existing context rather than
background context in bindMount() so that span exists as a child of a
parent span.

72cb9287a0 vhost-user-blk: Use PciPath type for vhost user devices
VhostUserDeviceAttrs::PCIAddr didn't actually store a PCI address
(DDDD:BB:DD.F), but rather a PCI path.  Use the PciPath type and
rename things to make that clearer.

TestHandleBlockVolume previously used the bizarre value "0001:01"
which is neither a PCI address nor a PCI path for this value.  Change
it to a valid PCI path - it appears the actual value didn't matter for
that test, as long as it was consistent.

74f5b5febe runtime/block: Use PciPath type through block code
BlockDrive::PCIAddr doesn't actually store a PCI address
(DDDD:BB:DD.F) but a PCI path.  Use the PciPath type and rename things
to make that clearer.

TestHandleBlockVolume() previously used a bizarre value "0002:01" for
the "PCI address" which was neither an actual PCI address, nor a PCI
path.  Update it to use a PCI path - the actual value appears not to
matter in this test, as long as its consistent throughout.

92dfa4634b drivers: Correct isPCIeDevice logic
Currently, isPCIeDevice() attempts to determine if a (host) device is
PCI-Express capable by looking up its link speed via the PCI slots
information in sysfs.  This is a) complicated and b) wrong.  PCI-e
devices don't have to have slots information, so this frequently fails.

Instead determine if devices are PCI-e by checking for the presence of
PCIe extended configuration space by looking at the size of the "config"
file in sysfs.

Forward ported from 6bf93b23 in the Kata 1.x runtime repository.
