abf12f071b conf: checkpoint: Don't require <domain> when redefining checkpoints
The domain definition stored with a checkpoint isn't used currently
apart from matching disks when creating a new checkpoints.

As some users of the incremental backup API want to provide backups in
offline mode under their control (obviously while compying with our
documentation on how the on-disk state should be handled) and then want
to define the checkpoint for live use, supplying a <domain> sub-element
is overly complex and not actually needed by the code.

Relax the restriction when re-defining a checkpoint so that <domain> is
not necessary and add (alibistic) documentation saying that future
actions may not work if it's missing.

3fc4412c6f qemu: support kvm-poll-control performance hint
QEMU version 4.2 introduced a performance feature under commit
d645e13287 ("kvm: i386: halt poll control MSR support").

This patch adds a new KVM feature 'poll-control' to set this performance
hint for KVM guests. The feature is off by default.

To enable this hint and have libvirt add "-cpu host,kvm-poll-control=on"
to the QEMU command line, the following XML code needs to be added to the
guest's domain description:

  <features>
    <kvm>
      <poll-control state='on'/>
    </kvm>
  </features>

9fd2e78b96 docs: xsl: Unify stylability of main container element
page.xsl was adding '<div id="content">' wrapper for the content picked
up from the <body> element from the original input file. Optionally
class="$DOCNAME" was added for some documents taken from <body>.

Since docs generated from RST by docutils have a '<div class='document'
id='$DOCNAME>' we actually don't need an extra wrapper for them.

Additionally if we standardize on one of them we can use the same styles
for both. I've picked the latter because it makes more sense to use the
document name as 'id'.

This patch:
1) Modifies the XSL trasformation to add the wrapper only if it's not
   present.

2) Modifies the XSL transformation to use 'id' for document name and
   class='document' for the wrapper element.

3) Changes docs.html/index.html/hvsupport.html to use 'id' instead of
   'class' for document name.

4) Modifies the main stylesheet to keep styling the elements properly
