This is the refactor of split ring as well as a helper to expanding
device and driver area size calculation for packed ring.

one which is supposed to have better cache utilization and more

  tests/virtio-blk-test: read config space after feature negotiation

The VIRTIO Configuration Space cannot be accessed before device feature
bits have been read because a driver doesn't know the endianness until
it has checked VIRTIO_F_VERSION_1.

Fix this problem in preparation for VIRTIO 1.0 support.

  libqos: read QVIRTIO_MMIO_VERSION register

There was no real virtio-mmio ABI change between Legacy and VIRTIO 1.0
except that the Version field was incremented from 1 to 2.

However, QEMU does not allow Legacy drivers to perform VIRTIO 1.0
operations like accessing 64-bit feature bits.  Since we will introduce
64-bit feature bit support we need a way to differentiate between
virtio-mmio Version 1 and 2 to avoid upsetting QEMU when we operate in
Legacy mode.

Stash away the Version field so later patches can change behavior
depending on the version.

  libqos: extend feature bits to 64-bit

In VIRTIO 1.0 feature bits changed from 32-bit to 64-bit.  (In fact, the
transports allow even more feature bits but nothing uses more than 64
bits today.)

Add 64-bit feature bit support to virtio-mmio and virtio-pci.  This will
be necessary for VIRTIO 1.0 support.

  virtio-scsi-test: add missing feature negotiation

virtio-scsi-test.c is non-compliant.

libqos tests acknowledge all feature bits advertised by the device,
except VIRTIO_F_BAD_FEATURE (which devices use to detect broken
drivers!) and VIRTIO_RING_F_EVENT_IDX (which is not implemented in
libqos and accepting it would break notifications).

VIRTIO Device Initialization requires that feature negotiation has
completed before virtqueues are set up.  This makes sense because the
driver must know whether it is operating in Legacy or VIRTIO 1.0 mode
before it can access vring fields with the correct endianness.

  libqos: implement VIRTIO 1.0 FEATURES_OK step

Device initialization has an extra step in VIRTIO 1.0.  The FEATURES_OK
status bit is set to indicate that feature negotiation has completed.
The driver then reads the status register again to check that the device
agrees with the final features.

Implement this step as part of qvirtio_set_features() instead of
introducing a separate function.  This way all existing code works
without modifications.

The check in qvirtio_set_driver_ok() needs to be updated because
FEATURES_OK will be set for VIRTIO 1.0 devices.

  libqos: add VIRTIO PCI 1.0 support

Implement the VIRTIO 1.0 virtio-pci interface.  The main change here is
that the register layout is no longer a fixed layout in BAR 0.  Instead
we have to iterate of PCI Capabilities to find descriptions of where
various registers are located.  The vring registers are also more
fine-grained, allowing for more flexible vring layouts, but we don't
take advantage of that.

  virtio: drop unused virtio_device_stop_ioeventfd() function

virtio_device_stop_ioeventfd() has not been used since commit
310837de6c1e0badfd736b1b316b1698c53120a7 ("virtio: introduce
grab/release_ioeventfd to fix vhost") in 2016.

Nowadays ioeventfd is stopped implicitly by the virtio transport when
lifecycle events such as the VM pausing or device unplug occur.
