9985f62b51 qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
As advertised in previous commit, this event is delivered to us
when virtio-mem module changes the allocation inside the guest.
It comes with one attribute - size - which holds the new size of
the virtio-mem (well, allocated size), in bytes.
Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.

This current size is reported in the domain XML as an output
element only.

56fbabf1a1 Add basic driver for the Cloud-Hypervisor
Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.

The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).

This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
 * vm.create
 * vm.delete
 * vm.boot
 * vm.shutdown
 * vm.reboot
 * vm.pause
 * vm.resume

To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.

Some additional notes:
 * The curl handle is persistent but not useful to detect ch process
 shutdown/crash (a future patch will address this shortcoming)
 * On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
 emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
 32-bit userspace is fine, a 32-bit kernel isn't validated)

c2707c7e3c lib: Add win-dmp crashdump format
QEMU gained support for 'win-dmp' format in it's release of 3.0,
but libvirt doesn't implement it yet. Fortunately, there not much
needed: new value to virDomainCoreDumpFormat public enum, which
unfortunately means that QEMU driver has to be updated in the
same commit, because of VIR_ENUM_IMPL().

Luckily, we don't need any extra QEMU capability - the code
already checks supported formats via
'query-dump-guest-memory-capability' just before issuing
'dump-guest-memory'.

c80911f2de src: define virDomainGetMessages API
This API allows fetching a list of informational messages recorded
against the domain. This provides a way to give information about
tainting of the guest due to undesirable actions/configs, as well
as provide details of deprecated features.

The output of this API is explicitly targetted at humans, not
machines, so it is inappropriate to attempt to pattern match on
the strings and take action off them, not least because the messages
are marked for translation.

Should there be a demand for machine targetted information, this
would have to be addressed via a new API, and is not planned at
this point in time.

de0b6dd63e Introduce OpenSSH authorized key file mgmt APIs
When setting up a new guest or when a management software wants
to allow access to an existing guest the
virDomainSetUserPassword() API can be used, but that might be not
good enough if user want to ssh into the guest. Not only sshd has
to be configured to accept password authentication (which is
usually not the case for root), user have to type in their
password. Using SSH keys is more convenient. Therefore, two new
APIs are introduced:

virDomainAuthorizedSSHKeysGet() which lists authorized keys for
given user, and

virDomainAuthorizedSSHKeysSet() which modifies the authorized
keys file for given user (append, set or remove keys from the
file).

It's worth nothing that while authorized_keys file entries have
some structure (as defined by sshd(8)), expressing that structure
goes beyond libvirt's focus and thus "keys" are nothing but an
opaque string to libvirt.

NOTE: normally the 'parent' would be a PCI device instead of 'computer',

doesn't have a normal parent device.
