2968e5ff3a bhyve: add support for setting fbuf resolution
The resolution of the VNC framebuffer can now be set via the resolution
definition introduced in 5.9.0.

Also, add "gop" to the list of model types  the <resolution/>
sub-element is valid for.

63af8fdeb2 qemu: revert latest pSeries NVDIMM design changes
In [1], changes were made to remove the existing auto-alignment
for pSeries NVDIMM devices. That design promotes strange situations
where the NVDIMM size reported in the domain XML is different
from what QEMU is actually using. We removed the auto-alignment
and relied on standard size validation.

However, this goes against Libvirt design philosophy of not
tampering with existing guest behavior, as pointed out by Daniel
in [2]. Since we can't know for sure whether there are guests that
are relying on the auto-alignment feature to work, the changes
made in [1] are a direct violation of this rule.

This patch reverts [1] entirely, re-enabling auto-alignment for
pSeries NVDIMM as it was before. Changes will be made to ease
the limitations of this design without hurting existing
guests.

This reverts the following commits:

- commit 2d93cbdea9
  Revert "formatdomain.html.in: mention pSeries NVDIMM 'align down' mechanic"

- commit 0ee56369c8
  qemu_domain.c: change qemuDomainMemoryDeviceAlignSize() return type

2ce20ba839 docs: Discourage users from using fwcfg
Even though this was brought up in upstream discussion [1] it
missed my patches: users should prefer <oemStrings/> over fwcfg.
The reason is that fwcfg is considered somewhat internal to QEMU
and it has limited number of slots and neither of these applies
to <oemStrings/>.

While I'm at it, I'm fixing the example too (because it contains
incorrect element name) and clarifying sysfs/ exposure.

9d15647dcb Xen: Add writeFiltering option for PCI devices
By default Xen only allows guests to write "known safe" values into PCI
configuration space, yet many devices require writes to other areas of
the configuration space in order to operate properly. To allow writing
any values Xen supports the 'permissive' setting, see xl.cfg(5) man page.

This change models Xen's permissive setting by adding a writeFiltering
attribute on the <source> element of a PCI hostdev. When writeFiltering
is set to 'no', the Xen permissive setting will be enabled and guests
will be able to write any values into the device's configuration space.
The permissive setting remains disabled in the absense of the
writeFiltering attribute, of if it is explicitly set to 'yes'.

For now just plain conversion to rst. Anchors which existed until now
are preserved, but the table of contents now uses the docutils-generated
ones.

Additionally <code> which was nested in a link (<a>) was removed as rst
doesn't support nesting of inline markup.

The only anchor which wasn't restored is
'elementsDiskBackingStoreIndex' and its only reference was removed.
