'migration_disks' is a NULL-terminated string list, so the code can be
converted to either iterate the string-list, use existing accessors or
check the presence of the pointers instead of checking the count.

The actual number of disks to migrate is not important. The presence of
disks to migrate can be inferred from presence of the 'migrate_disks'
pointer which is logged.
Since 'nmigrate_disks' will eventually be removed remove the logging

The function open-coded the checking whether a disk is being migrated

'virTypedParamsGetStringList' fills the returned array only with string
parameters with matching name. The filtering code though leaves the
possibility that all items are filtered out but the return array is
still (over)allocated.
Since 'virTypedParamsFilter()' now also allows filtering by type we can
move the filtering there ensuring that we always allocate the right
number of elements and more importantly the returned array will be NULL
if none elements are present.
Rework the code and adjust docs.

The only caller of this function is doing some additional filtering so
it's useful if the filtering function was able to do so internally.
Introduce a 'type' parameter which will optionally filter the results by

Use automatic freeing, declare one variable per line and return early
when possible. As this is an internal helper there's no need to check

The 'virTypedParamsFilter' function can't fail and thus it never returns
negative values. Change the return type to 'size_t' and adjust callers
to not check the return value for being negative.
Adjust the docs to hilight this and also the fact that the filtered
typed param list returned via @ret is not a deep copy and thus callers
must not use the common function to free it.

Specify that the <allocation> parameter for the newly-created qcow2

The 'disk->mirrorJob' and 'disk->mirrorState' fields need to be cleared
after a blockjob, but should be kept around while 'disk->mirror' is
still in place. As 'disk->mirror' is cleared only after conclusion of
the job in 'qemuBlockJobEventProcessConcluded()' we should be resetting
them only afterwards.
Move the code later, but since the job is unregistered from the disk we
need to store the pointer to the disk before concluding the job.

When concluding a job with a 'mirror' we first unplugged the appropriate
no-longer used images from qemu and then updated the definition.
Normally this wouldn't be a problem because for any other thread this is
done under the VM lock thus atomic. Unfortunately though, the AppArmor
security backend is using a VM XML to pass data to the helper process
and the state of the definition at that point was unsuitable to format a
valid XML thus making 'virt-aa-helper' report parsing failure.
Since we're removing the images the proper state of the VM definition
indeed should not include the mirror element any more at the point when
the images are removed.

Commit a37bd2a15b eliminated a failure
to update *any* change in an interface that was connected via a
network that consisted of a pool of VFs using macvtap passthrough
mode. Unfortunately it caused a regression that results in failure to
update changes to bandwidth/vlan/trustGuestRxFilters in any interface
connected via a network that uses a bridge to connect tap devices.
This fixes that problem by narrowing the usage of the fix in the
earlier patch to only be done in the case that the the interface is
connected via a macvtap+passthrough network.

The model was defined with two CPU features that cannot be explicitly
configured in QEMU (it knows the MSR bits, but there's no name
associated with them). The features should have never existed in the CPU
map. While removing them from the list of features and existing CPU
models is not trivial (to avoid compatibility issues), we can at least
fix the SierraForest CPU model added in this release cycle.
The rest will be handled later in a separate series.

QEMU uses Linux extensions to madvise() to include/exclude guest
memory from core dump. These are obviously not available
everywhere. Currently, users have two options:
1) configure <memory dumpCore=''/> in domain XML, or
2) configure dump_guest_core in qemu.conf
While these work, they may harm user experience as "things just
don't work" out of the box. Provide sane default in
virQEMUDriverConfigNew() so neither of two options is required.
To have predictable results in tests, explicitly set
cfg->dumpGuestCore to false in qemuTestDriverInit() (which
creates cfg object for tests).
