The ACPI PIIX4 device in QEMU upstream as not the same behavior to
handle PCI hotplug. This patch introduce the necessary change to the
DSDT ACPI table to behave as expceted by the new QEMU.
To switch to this new DSDT table version, there is a new option
--dm-version to mk_dsdt.
Change are inspired by SeaBIOS DSDT source code.
There is few things missing with the new QEMU:
- QEMU provide the plugged/unplugged status only per slot (and not
per func like qemu-xen-traditionnal.
- I did not include the _STA ACPI method that give the status of a
device (present, functionning properly) because qemu-xen does not
handle it.
- I did not include the _RMV method that say if the device can be
removed,
because the IO port of QEMU that give this status always return
true. In
SeaBIOS table, they have a specific _RMV method for VGA, ISA that
return
false. But I'm not sure that we can do the same in Xen.
So, the only way to remove a device is from outside of the guest (like
with xl pci-detatch), and can not be initiated from inside.

Two functions are provided. TYPE_gen_json exposes an interface which is
compatible with the YAGL generator infrastructure. TYPE_to_string uses this to
produce a pretty printed string.
The TYPE_gen_json functions are defined in a new header libxl_json.h which is
not exposed via libxl.h due to the use of YAGL datatypes to avoid poluting the
namespace us libxl users which don't use the library themselves. If a libxl
user is interested in integrating at the YAGL level then it should #include
this file itself.
Also update testidl to generate a random version of each IDL datastructure and
convert it to JSON. Unfortunately this requires a libxl_ctx and therefore the
test must be run on a Xen system now.

Evict of a nominated gfn must fail if some other process mapped the
page without checking the p2mt of that gfn first.
Add a check to cancel eviction if the page usage count is not 1.
Handle the possible eviction failure in the page-in paths.
After nominate and before evict, something may check the p2mt and call
populate. Handle this case and let the gfn enter the page-in path. The
gfn may still be connected to a mfn, so there is no need to allocate a
new page in prep.
Adjust do_mmu_update to return -ENOENT only if the gfn has entered the
page-in path and if it is not yet connected to a mfn. Otherwise
linux_privcmd_map_foreign_bulk() may loop forever.
Add MEM_EVENT_FLAG_EVICT_FAIL to inform pager that a page-in request for
a possible not-evicted page was sent. xenpaging does currently not need
that flag because failure to evict a gfn will be caught.

toplevel Xenstore and Xenbus modules.
xb becomes xenbus, xc becomes xenctrl, xl becomes xenlight,
xs becomes xenstore, eventchn becomes xeneventchn and
