Elizabeth Ashurov 1c90e89e64 qga/vss-win32: Add VSS provider unregistration retry 
This commit improves the QGA VSS provider installation flow by attempting to unregister the VSS provider if it's already
found during installation. This allows for a retry of installation even if a previous unregistration failed or was not performed.
This will prevent inconsistencies between QGA and QGA-VSS versions.
Before this commit, QGA can use QGA-VSS from the previous installation.

Kostiantyn Kostiuk 012bb70cd1 qga-vss: Exit with non-zero code when register fail 
QGA installer uses rundll32 to run the DLLCOMRegister function
from qga-vss.dll and perform VSS provider registration.
rundll32 ignores the return value of the function and always
exits with a zero exit code. This causes a situation where
the installer does not know the status of VSS provider registration.

This commit forces to change exit code when the VSS provider
registration fails.

Thanos Makatos da198e8f0f vfio-user: introduce vfio-user protocol specification 
This patch introduces the vfio-user protocol specification (formerly
known as VFIO-over-socket), which is designed to allow devices to be
emulated outside QEMU, in a separate process. vfio-user reuses the
existing VFIO defines, structs and concepts.

It has been earlier discussed as an RFC in:
"RFC: use VFIO over a UNIX domain socket to implement device offloading"

For performance, we only wait for the message responses when we're doing
with a series of updates via the listener_commit() callback.

John Levon 9fca2b7d70 vfio-user: add vfio-user class and container 
Introduce basic plumbing for vfio-user with CONFIG_VFIO_USER.

We introduce VFIOUserContainer in hw/vfio-user/container.c, which is a
container type for the "IOMMU" type "vfio-iommu-user", and share some
common container code from hw/vfio/container.c.

Add hw/vfio-user/pci.c for instantiating VFIOUserPCIDevice objects,
sharing some common code from hw/vfio/pci.c.

Shalini Chellathurai Saroja 435c758da1 hw/s390x: add SCLP event type CPI 
Implement the Service-Call Logical Processor (SCLP) event
type Control-Program Identification (CPI) in QEMU. This
event is used to send CPI identifiers from the guest to the
host. The CPI identifiers are: system type, system name,
system level and sysplex name.

System type: operating system of the guest (e.g. "LINUX   ").
System name: user configurable name of the guest (e.g. "TESTVM  ").
System level: distribution and kernel version, if the system type is Linux
(e.g. 74872343805430528).
Sysplex name: name of the cluster which the guest belongs to (if any)
(e.g. "PLEX").

The SCLP event CPI is supported only from "s390-ccw-virtio-10.1" machine
and higher.
