dddcb601eb qemu_migration: Avoid writing to freed memory
When a domain is killed on the source host while it is being migrated
and libvirtd is waiting for the migration to finish (waiting for the
domain condition in qemuMigrationSrcWaitForCompletion), the run-time
state including priv->job.current may already be freed once
virDomainObjWait returns with -1. Thus the priv->job.current pointer
cached in jobInfo is no longer valid and setting jobInfo->status may
crash the daemon.

0a476f1521 conf: Introduce virDomainDefPostParseMemtune
Previously we were ignoring "nodeset" attribute for hugepage pages
if there was no guest NUMA topology configured in the domain XML.
Commit <fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5> partially fixed
that issue but it introduced a somehow valid regression.

In case that there is no guest NUMA topology configured and the
"nodeset" attribute is set to "0" it was accepted and was working
properly even though it was not completely valid XML.

This patch introduces a workaround that it will ignore the nodeset="0"
only in case that there is no guest NUMA topology in order not to
hit the validation error.

After this commit the following XML configuration is valid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
    </hugepages>
  </memoryBacking>

but this configuration remains invalid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
      <page size='1048576' unit='KiB'/>
    </hugepages>
  </memoryBacking>

The issue with the second configuration is that it was originally
working, however changing the order of the <page> elements resolved
into using different page size for the guest.  The code is written
in a way that it expect only one page configured and always uses only
the first page in case that there is no guest NUMA topology configured.
See qemuBuildMemPathStr() function for details.

5c93dfb46d conf: Move hugepage XML validation check out of qemu_command
We can safely validate the hugepage nodeset attribute at a define time.
This validation is not done for already existing domains when the daemon
is restarted.

All the changes to the tests are necessary because we move the error
from domain start into XML parse.

154b08a3a7 tests: introduce hugepages-nodeset
This use-case was broken by commit
<fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5>.

We allowed this configuration and it was working as expected therefore
we can consider it as regression.  We should have never allowed such
configuration so now the best solution is in case of non-numa guest
silently ignore the 'nodeset' attribute if it's set to '0'.

That will be fixed by following patches.

6ff69e936e tests: introduce hugepages-default-1G-nodeset-2M
This test case is currently working but it uncovers existing issue
in our code that the generated QEMU commandline uses the default 1G
hugepage instead of the 2M hugepage specified for exact node.

The issue in our code is that for non-numa guests we take into account
only the first hugepage.  This will be fixed as invalid configuration
since it doesn't make any sense to set default and specific hugepage
for non-numa guest.
