2d5f7a49ae qemu: Implement the IBS pSeries feature
This patch adds the implementation of the IBS pSeries feature,
using the QEMU_CAPS_MACHINE_PSERIES_CAP_IBS capability added
in the previous patch.

IBS can have the following values: "broken", "workaround",
"fixed-ibs", "fixed-ccd" and "fixed-na".

This is the XML format for the cap:

<features>
  <ibs value='fixed-ibs'/>
</features>

104dadcff6 qemu: Implement the SBBC pSeries feature
This patch adds the implementation of the SBBC pSeries feature,
using the QEMU_CAPS_MACHINE_PSERIES_CAP_SBBC capability added
in the previous patch.

Like the previously added CFPC feature, SBBC can have the values
"broken", "workaround" or "fixed". Extra code is required to handle
it since it's not a regular tristate capability.

This is the XML format for the cap:

<features>
  <sbbc value='workaround'/>

b7d6648d43 conf: add xen specific feature: e820_host
e820_host is a Xen-specific option, only available for PV domains, that
provides the domain a virtual e820 memory map based on the host one. It
is enabled with a new Xen hypervisor feature, e.g.

  <features>
    <xen>
      <e820_host state='on'/>
    </xen>
  </features>

e820_host is required when using PCI passthrough and is generally
considered safe for any PV kernel. e820_host is silently ignored if set
in HVM domain configuration. See xl.cfg(5) man page in the Xen
documentation for more details.

2d3cf60328 qemu: hook up pcie-root-port hotplug='off' option
If a pcie-root-port or pcie-downstream-port has hotplug='off' in its
<target> subelement, and if the qemu binary supports the hotplug=false
option, then it will be added to the commandline for the pcie
controller. This controller will then not allow any hotplug/unplug of
devices while the guest is running (and the hotplug capability won't
be advertised to the guest OS, so the guest OS also won't present
unplugging of PCI devices as an option).

  <controller type='pci' model='pcie-root-port'>
    <target hotplug='off'/>
  </controller>

For any PCI controllers other than pcie-downstream-port and
pcie-root-port, of for qemu binaries that don't support the hotplug
commandline option, an error will be logged during validation.

Introduced in v1.2.17-rc1~121, the assumption was that the
driver->privileged is immutable at the time but it might change
in the future. Well, it did not ever since. It is still immutable
variable. Drop the needless accessor then.
