  vhost-user: add new vhost user messages to support virtio config space

Add VHOST_USER_GET_CONFIG/VHOST_USER_SET_CONFIG messages which can be
used for live migration of vhost user devices, also vhost user devices
can benefit from the messages to get/set virtio config space from/to the
I/O target. For the purpose to support virtio config space change,
VHOST_USER_SLAVE_CONFIG_CHANGE_MSG message is added as the event notifier
in case virtio config space change in the slave I/O target.

  vhost-user-blk: introduce a new vhost-user-blk host device

This commit introduces a new vhost-user device for block, it uses a
chardev to connect with the backend, same with Qemu virito-blk device,
Guest OS still uses the virtio-blk frontend driver.

To use it, start QEMU with command line like this:

qemu-system-x86_64 \
    -chardev socket,id=char0,path=/path/vhost.socket \
    -device vhost-user-blk-pci,chardev=char0,num-queues=2, \
      bootindex=2... \

Users can use different parameters for `num-queues` and `bootindex`.

Different with exist Qemu virtio-blk host device, it makes more easy
for users to implement their own I/O processing logic, such as all
user space I/O stack against hardware block device. It uses the new
vhost messages(VHOST_USER_GET_CONFIG) to get block virtio config
information from backend process.

This change supports running the virtio_bus_set_host_notifier

  virtio: improve virtio devices initialization time

The loading time of a VM is quite significant when its virtio
devices use a large amount of virt-queues (e.g. a virtio-serial
device with max_ports=511). Most of the time is spend in the
creation of all the required event notifiers (ioeventfd and memory
regions).

This patch pack all the changes to the memory regions in a
single memory transaction.

  intel-iommu: Redefine macros to enable supporting 48 bit address width

The current implementation of Intel IOMMU code only supports 39 bits
host/iova address width so number of macros use hard coded values based
on that. This patch is to redefine them so they can be used with
variable address widths. This patch doesn't add any new functionality
but enables adding support for 48 bit address width.

  intel-iommu: Extend address width to 48 bits

The current implementation of Intel IOMMU code only supports 39 bits
iova address width. This patch provides a new parameter (x-aw-bits)
for intel-iommu to extend its address width to 48 bits but keeping the
default the same (39 bits). The reason for not changing the default
is to avoid potential compatibility problems with live migration of
intel-iommu enabled QEMU guest. The only valid values for 'x-aw-bits'
parameter are 39 and 48.

After enabling larger address width (48), we should be able to map
larger iova addresses in the guest. For example, a QEMU guest that
is configured with large memory ( >=1TB ). To check whether 48 bits
aw is enabled, we can grep in the guest dmesg output with line:
"DMAR: Host address width 48".

If we try to use more pcie_root_ports then available slots
and an IO hint is passed to the port, QEMU crashes because
we try to init the "IO hint" capability even if the device
is not created.
Fix it by checking for error before adding the capability,
so QEMU can fail gracefully.

  ACPI/unit-test: Add a testcase for RAM allocation in numa node

As QEMU supports the memory-less node, it is possible that there is
no RAM in the first numa node(also be called as node0). eg:
  ... \
  -m 128,slots=3,maxmem=1G \
  -numa node -numa node,mem=128M \

But, this makes it hard for QEMU to build a known-to-work ACPI SRAT
table. Only fixing it is not enough.

Add a testcase for this situation to make sure the ACPI table is
correct for guest.

  tests: acpi: move tested tables array allocation outside of 
test_acpi_dsdt_table()

at best it's confusing that array for list of tables to be tested
against reference tables is allocated within test_acpi_dsdt_table()
and at worst it would just overwrite list of tables if they were
added before test_acpi_dsdt_table().
Move array initialization to test_acpi_one() before we start
processing tables.

  tests: acpi: rename test_acpi_tables()/test_dst_table() to reflect its usage

Main purpose of test_dst_table() is loading a table from QEMU
with checking that checksum in header matches actual one,
rename it reflect main action it performs.

Likewise test_acpi_tables() name is to broad, while the function
only loads tables referenced by RSDT, rename it to reflect it.

  vhost-user: fix misaligned access to payload

We currently take a pointer to a misaligned field of a packed structure.
clang reports this as a build warning.
A fix is to keep payload in a separate structure, and access is it
from there using a vectored write.

  vhost: remove assertion to prevent crash

QEMU will assert on vhost-user backed virtio device hotplug if QEMU is
using more RAM regions than VHOST_MEMORY_MAX_NREGIONS (for example if
it were started with a lot of DIMM devices).

Fix it by returning error instead of asserting and let callers of
vhost_set_mem_table() handle error condition gracefully.
