[PMM changes:
 * fixed trivial makefile conflict
 * removed unused int_enable
 * host_features doesn't need migrating
 * reset guest accessible state in the reset function
 * minor style fixes like extra blank lines
 * RAZ/WI if there's no backend
 * made transport size 0x200, in line with kvmtool
 * set has_variable_vring_alignment

      virtio: Support transports which can specify the vring alignment · 6ce69d1c
      由 Peter Maydell 提交于 
      Support virtio transports which can specify the vring alignment
(ie where the guest communicates this to the host) by providing
a new virtio_queue_set_align() function. (The default alignment
remains as before.)

Transports which wish to make use of this must set the
has_variable_vring_alignment field in their VirtioBusClass
struct to true; they can then change the alignment via
virtio_queue_set_align().

      virtio: Add support for guest setting of queue size · e63c0ba1
      由 Peter Maydell 提交于 
      The MMIO virtio transport spec allows the guest to tell the host how
large the queue size is. Add virtio_queue_set_num() function which
implements this in the QEMU common virtio support code.

      dataplane: sync virtio.c and vring.c virtqueue state · 9154b02c
      由 Stefan Hajnoczi 提交于 
      Load the virtio.c state into vring.c when we start dataplane mode and
vice versa when stopping dataplane mode.  This patch makes it possible
to start and stop dataplane any time while the guest is running.

This will eventually allow us to go back to QEMU main loop for
bdrv_drain_all() and live migration.  In the meantime, this patch makes
the dataplane lifecycle more robust but should make no visible
difference.  It may be useful in the virtio-net dataplane effort.

      memory: make section size a 128-bit integer · 052e87b0
      由 Paolo Bonzini 提交于 
      So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes

An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

      qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path · bbfa18fc
      由 Amos Kong 提交于 
      Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

v2: only add nothing to fw_dev_path when get_fw_dev_path() is
    implemented and returns NULL. then it will not effect other devices
    don't have get_fw_dev_path() implementation.
v3: implement default get_fw_dev_path() in BusClass
