QEMU will crash when device-memory-region-size property is read if ms->device_memory
wasn't initialized yet.
Crash can be reproduced with:
$QEMU -preconfig -qmp unix:qmp_socket,server,nowait &
./scripts/qmp/qom-get -s qmp_socket /machine.device-memory-region-size
Instead of crashing return 0 if ms->device_memory hasn't been initialized.

In new sockets/dies/cores/threads model, the apicid of logical cpu could
imply die level info of guest cpu topology thus x86_apicid_from_cpu_idx()
need to be refactored with #dies value, so does apicid_*_offset().
To keep semantic compatibility, the legacy pkg_offset which helps to
generate CPUIDs such as 0x3 for L3 cache should be mapping to die_offset.

The "Multiple queue support" section makes references to vhost-user-net
"queue pairs". This is confusing for two reasons:
1. This actually applies to all device types, not just vhost-user-net.
2. VHOST_USER_GET_QUEUE_NUM returns the number of virtqueues, not the
number of queue pairs.
Reword the section so that the vhost-user-net specific part is relegated
to the very end: we acknowledge that vhost-user-net historically
automatically enabled the first queue pair.

Existing vhost-user device backends, including vhost-user-scsi and
vhost-user-blk, support multiqueue but libvhost-user currently does not
advertise this.
VHOST_USER_PROTOCOL_F_MQ enables the VHOST_USER_GET_QUEUE_NUM request
needed for a vhost-user master to query the number of queues. For
example, QEMU's vhost-user-net master depends on
VHOST_USER_PROTOCOL_F_MQ for multiqueue.
If you're wondering how any device backend with more than one virtqueue
functions today, it's because device types with a fixed number of
virtqueues do not require querying the number of queues. Therefore the
vhost-user master for vhost-user-input with 2 virtqueues, for example,
doesn't actually depend on VHOST_USER_PROTOCOL_F_MQ. It just enables
virtqueues 0 and 1 without asking.
Let there be multiqueue!

Currently libvhost-user is hardcoded to at most 8 virtqueues. The
device backend should decide the number of virtqueues, not
libvhost-user. This is important for multiqueue device backends where
the guest driver needs an accurate number of virtqueues.
This change breaks libvhost-user and libvhost-user-glib API stability.
There is no stability guarantee yet, so make this change now and update
all in-tree library users.
This patch touches up vhost-user-blk, vhost-user-gpu, vhost-user-input,
vhost-user-scsi, and vhost-user-bridge. If the device has a fixed
number of queues that exact number is used. Otherwise the previous
default of 8 virtqueues is used.
vu_init() and vug_init() can now fail if malloc() returns NULL. I
considered aborting with an error in libvhost-user but it should be safe
to instantiate new vhost-user instances at runtime without risk of
terminating the process. Therefore callers need to handle the vu_init()
failure now.
vhost-user-blk and vhost-user-scsi duplicate virtqueue index checks that
are already performed by libvhost-user. This code would need to be
modified to use max_queues but remove it completely instead since it's
redundant.

The VhostUserMsg request is reused as the reply by message processing
functions. This is risky since request fields may corrupt the reply if
the vhost-user message handler function forgets to re-initialize them.
Changing this practice would be very invasive but we can introduce a

code duplication in message processing functions.

some properties: "ioeventfd" and "vectors". This may cause various
issues, such as failing migration or invalid properties.
Since those VirtioPCI devices do not have a base name, their class are
initialized with virtio_pci_generic_base_class_init(). However, if the
VirtioPCIDeviceTypeInfo provided a class_init which sets dc->props,
the properties were overwritten by virtio_pci_generic_class_init().
Instead, introduce an intermediary base-type to register the generic
properties.

Override the device hotplug handler to properly handle the memory device
part via virtio-pmem-pci callbacks from the machine hotplug handler and
forward to the actual PCI bus hotplug handler.
As PCI hotplug has not been properly factored out into hotplug handlers,
most magic is performed in the (un)realize functions. Also some PCI host
buses don't have a PCI hotplug handler at all yet, just to be sure that
we alway have a hotplug handler on x86, add a simple error check.
Unlocking virtio-pmem will unlock virtio-pmem-pci.

We need a proxy device for virtio-pmem, and this device has to be the
actual memory device so we can cleanly hotplug it.
Forward memory device class functions either to the actual device or use
properties of the virtio-pmem device to implement these in the proxy.
virtio-pmem will only be compiled for selected, supported architectures
(that can deal with virtio/pci devices being memory devices). An
architecture that is prepared for that can simply enable
CONFIG_VIRTIO_PMEM to make it work.
As not all architectures support memory devices (and CONFIG_VIRTIO_PMEM
will be enabled per supported architecture), we have to move the PCI proxy
to a separate file.

Add linux headers for virtio pmem. These are not yet upstream - include
them temporarily as merge window in which this is supposed to be is
coming up shortly. If virtio-pmem ends up not being merged
then this will be reverted and accordingly virtio-pmem dropped.

Commit 2d384d7c8 broken the build when built with:
configure --without-default-devices --disable-user
The reason was the conversion of cpu->hyperv_synic to
cpu->hyperv_synic_kvm_only although the rest of the patch introduces a
feature checking mechanism. So I've fixed the KVM_EXIT_HYPERV_SYNIC in
hyperv-stub to do the same feature check as in the real hyperv.c

It's fairly common to build qemu-user binaries with --static linking
so the binary can be copied around without libraries. Enable --static
in the default qemu-user build to cover this.
There are other qemu-user builds that use dynamic linking so they
should catch any problems there.

Yes, we have docker images for fedora. But for trouble-shooting it
might be helpful to have a vm too. When vm builds fail you can use
it to figure whenever the vm setup or the guest os is the problem.
