clarify what version initial support was added, and when libvirt
started supporting it for the qemu driver

https://bugzilla.redhat.com/show_bug.cgi?id=657931

Added with commit 3b431929 in v1.2.2 but never documented

https://bugzilla.redhat.com/show_bug.cgi?id=1313613

We use device-mapper to enumerate all dm devices, and filter out
the list of multipath devices by checking the target_type string
name. The code however cancels all scanning if we encounter
target_type=NULL

I don't know how to reproduce that situation, but a user was hitting
it in their setup, and inspecting the lvm2/device-mapper code shows
many places where !target_type is explicitly ignored and processing
continues on to the next device. So I think we should do the same

The watchdog cli refactoring in 4666b762 dropped the temporary variable
we use to convert to action=dump to action=pause for the qemu cli, and
stored the converted value in the domain structure. Our other watchdog
handling code then treated it as though the user requested action=pause,
which broke action=dump handling.

Revive the temporary variable to fix things.

* Add a test for listen=XXX and <listen address=YYY/> collision error
* Add an explicit test for listen=XXX duplicated to <listen address=XXX/>
  We implicitly test it elsewhere but I figure it's better to be explicit,
  and this test case can be extended in the future for additional listen
  back compat if/when we support <listen type='socket'/> syntax

This allows tests to check for specific failure scenarios

In qemuHotplugCreateObjects, the ret variable was filled by
the value returned by qemuTestCapsCacheInsert.

If any of the functions after this assignment failed, we would still
return success.

Also adjust testCompareXMLToArgvHelper, where this change is just
cosmetic, because the value was overwritten right away.

Upcoming compression options for migration command patch
series hits current limit of 32 possible options for a command.
Lets take one step further and support 64 possible options.

And all it takes is moving from 32 bit integers to 64 bit ones.
The only less then trivial change i found is moving from
'ffs' to 'ffsl'.

SDK does not allocate memory when getting strings thus we
need to call every function that returns string twice.
First to obtain string length, second to obtain string
itself. It is tedious so let's create helper functions
for cases when we know length of the result beforehand
and we are not.

Lock driver when a new domain is created in prlsdkNewDomainByHandle

This patch introduces a new 'vzDriver' lockable object and provides
helper functions to allocate/destroy it and we pass it to prlsdkXxx
functions instead of virConnectPtr.
Now we store domain related objects such as domain list, capabitilies
etc. within a single vz_driver vzDriver structure, which is shared by
all driver connections. It is allocated during daemon initialization or
in a lazy manner when a new connection to 'vz' driver is established.
When a connection to vz daemon drops, vzDestroyConnection is called,
which in turn relays disconnect event to all connection to 'vz' driver.

Virtuozzo hypervisor supports native iomode.
So we should allow to add disk with iomode "native" or "default".

Trying to reload/SIGUSR1 virtlogd or virtlockd fails with:

error : virNetDaemonRun:747 : internal error: Not all servers restored, cannot run server

Commit 252610f7 changed the daemon state json to allow tracking
multiple servers. However it missed clearing dmn->srvObject after
the json is empty, like the previous code paths handled.  Later on in
virNewDaemonRun, dmn->srvObject is expected to be empty otherwise we
throw the above error.

Mock virNetDevRunEthernetScript instead.

This restores the VIR_TEST_REGENERATE_OUTPUT functionality.

This is just a wrapper for virCommand that takes two strings
and runs them.

Move it to virnetdev.c for easier mocking.

Since qemu is now able to notify us that the guest rejected the memory
unplug operation we can relay this to the user and make the API fail
right away.

Additionally document the possible values from the ACPI docs for future
reference.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1320447

The event is emitted on ACPI OSPM Status Indication events.

ACPI standard documentation describes the method as:

This object is an optional control method that is invoked by OSPM to
indicate processing status to the platform. During device ejection,
device hot add, or other event processing, OSPM may need to perform
specific handshaking with the platform. OSPM may also need to indicate
to the platform its inability to complete a requested operation; for
example, when a user presses an ejection button for a device that is
currently in use or is otherwise currently incapable of being ejected.
In this case, the processing of the ACPI Eject Request notification by
OSPM fails. OSPM may indicate this failure to the platform through the
invocation of the _OST control method. As a result of the status
notification indicating ejection failure, the platform may take certain
action including reissuing the notification or perhaps turning on an
appropriate indicator light to signal the failure to the user.

Since we didn't opt to use one single event for device lifecycle for a
VM we are missing one last event if the device removal failed. This
event will be emitted once we asked to eject the device but for some
reason it is not possible.

Similarly to the DEVICE_DELETED event we will be able to tell when
unplug of certain device types will be rejected by the guest OS. Wire up
the device deletion signalling code to allow handling this.

No need to keep two separate conditions. A slight juggling of return
values is needed to accomodate virDomainObjWaitUntil.

Neither of the callers cares whether the DEVICE_DELETED event isn't
supported or the event was received. Simplify the code and callers by
unifying the two values and changing the return value constants so that
a temporary variable can be omitted.

Callers ignore if this function returns -1 and continue as though the
DEVICE_DELETED event was not received. Since we can't be sure that the
event was not received we should behave as if the event was not
supported and remove the device definition right away. The error
fortunately won't really happen here.

The address assigning code might add new pci bridges.
We need them to have an alias when building the command line.

In real word usage, this is not a problem because all the code
paths already call qemuDomainAssignAddresses. However moving
this call lets us remove one extra call from qemuxml2argvtest.

It is only used for failed address allocation
Since we already have FLAG_EXPECT_FAILURE, use that instead.

Also unify the output to print the whole log buffer instead
of just the last error message.

After removing qemuBuildCommandLineCallbacks, testutilsqemu.h does not
need to include qemu_command.h.

Include just qemu_conf.h here and qemu_domain_address.h in files that
need it.

Essentially revert commit 3a6204cb which added these to allow the test
suite to pass without depending on the host system state.

Since commit 4b527c1a we already mock virSCSIDeviceGetSgName, so these
callbacks are useless.

Instead of calling the virDomainGraphicsListensParseXML function for all
graphics types and ignore the wrong ones move the call only to graphics
types where we supports listen elements.
