e87d4b9e2f qemu: drop QEMU_MIGRATION_COMPLETED_UPDATE_STATS
This way we get stats only in one place. The former code waits for
complete/postcopy status basically and don't need to mess with stats.

The patch drops raising an error on stats updates failure. This
does not make much sense anyway.

09f57f9aac qemu: introduce QEMU_DOMAIN_JOB_STATUS_POSTCOPY
Let's introduce QEMU_DOMAIN_JOB_STATUS_POSTCOPY state for job.current->status
instead of checking job.current->stats.status. The latter can be changed
when fetching migration statistics. Moving state function from the variable
and leave only store function seems more managable.

This patch removes all state checking usage of stats except for
qemuDomainGetJobStatsInternal. This place will be handled separately.

c57f3fd2f8 conf: Validate device on update-device
https://bugzilla.redhat.com/show_bug.cgi?id=1439991

Whenever a device is being updated via
virDomainUpdateDeviceFlags() API, we parse the device XML and
ideally run some generic checks to validate the configuration
(e.g. if device defines per-device boot order but the domain has
os/boot element already). Well, that's the theory - due to a
missing check we've jumped early from that check function.

5f5c515bbd event: ignore attempts to replace the event loop impl
Although not previously explicitly documented, the expectation for
the libvirt event loop is that an implementation is registered early
in application startup, before calling any libvirt APIs and then
run forever after. Replacing a previously registered event loop is
not safe & subject to races even if virConnectClose has been called
on open handles, due to delayed deregistration of callbacks during
conenction close.

Funny thing. So when initializing LXC driver's capabilities,
firstly the virLXCDriverGetCapabilities() is called. This creates
new capabilities, stores them under driver->caps, ref() them and
return them. However, the return value is ignored. Secondly, the
function is called yet again and since we have driver->caps set,
they are ref()-ed again an returned. So in the end, driver's
capabilities have refcount of three when in fact they should have
refcount of one.

4c10c38275 vmx: Expose VMware Managed Object Reference (moref) in XML.
If you use the VDDK library to access virtual machines remotely, you
really need to know the Managed Object Reference ("moref") of the VM.
This must be passed each time you connect to the API.

For example nbdkit's VDDK plugin requires a moref to be passed to
mount up a VM's disk remotely:

 nbdkit vddk user=root password=+/tmp/rootpw \
             server=esxi.example.com thumbprint=xx:xx:xx:... \
             vm=moref=2 \
             file="[datastore1] Fedora/Fedora.vmdk"

Getting the moref is a huge pain.  To get some idea of what it is, why
it is needed, and how much trouble it is to get it, see:
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.html
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-2-technical.html

However the moref is available conveniently in the internals of the
libvirt VMX driver.  This patch exposes it as a custom XML element
using the same "vmware:" namespace which was previously used for the
datacenterpath (see libvirt commit 636a990587).

It appears in the XML like this:

<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
  <name>Fedora</name>
...
  <vmware:datacenterpath>ha-datacenter</vmware:datacenterpath>
  <vmware:moref>2</vmware:moref>
</domain>

Note that the moref can appear as either a simple ID (for esx://
connections) or as a "vm-<ID>" (for vpx:// connections).  It should be
treated by users as an opaque string.

9820756cd3 qemu: handle -1 for pid in qemuDomainGetMachineName

start (after daemon start) pid is 0 and virSystemdGetMachineNameByPID

on next start virSystemdGetMachineNameByPID is called and returned an error.
Error is ignored so it is not critical. But at least on my system

this request.

be6a415e51 qemu: set bind mode for chardev while parsing XML
Currently while parsing domain XML we clear the UNIX path if it matches
one of the auto-generated paths by libvirt.  After that when the guest
is started new path is generated but the mode is also changed to "bind".

In the real-world use-case the mode should not change, it only happens
if a user provides a mode='connect' and path that matches one of the
auto-generated path or not provides a path at all.

Before *reconnect* feature was introduced there was no issue, but with
the new feature we need to make sure that it's used only with "connect"
mode, therefore we need to move the mode change into parsing in order
to have a proper error reported by validation code.

e4cb850081 rpc: avoid ssh interpreting malicious hostname as arguments
Inspired by the recent GIT / Mercurial security flaws
(http://blog.recurity-labs.com/2017-08-10/scm-vulns),
consider someone/something manages to feed libvirt a bogus
URI such as:

  virsh -c qemu+ssh://-oProxyCommand=gnome-calculator/system

In this case, the hosname "-oProxyCommand=gnome-calculator"
will get interpreted as an argument to ssh, not a hostname.
Fortunately, due to the set of args we have following the
hostname, SSH will then interpret our bit of shell script
that runs 'nc' on the remote host as a cipher name, which is
clearly invalid. This makes ssh exit during argv parsing and
so it never tries to run gnome-calculator.

We are lucky this time, but lets be more paranoid, by using
'--' to explicitly tell SSH when it has finished seeing
command line options. This forces it to interpret
"-oProxyCommand=gnome-calculator" as a hostname, and thus
see a fail from hostname lookup.

Our backing probing code handles directory file types properly in

alone.  However its caller, the virStorageFileGetMetadata() resets the
type to raw before probing, without even checking the type.  We need
to special-case TYPE_DIR in order to achieve desired results.

Also, in order to properly test this, we need to stop resetting format
of volumes in tests for TYPE_DIR (probably the reason why we didn't
catch that and why the test data didn't need to be modified).
