In 19284:0942BAA2A088 provision was made for running vnc and sdl
simultaneously. However, arrangements for saving and restoring the
new structure-configuration, and arrangements for allowing the new
code to load old savefiles, were not made.
This patch adds these facilities. Amongst other things, HVM VNC
save/restore will now work properly again.

Currently a slot may be specified for a hot-plug device,
but not for a pass-through device that is inserted at boot time.
This patch adds support for the latter.
The syntax is:
BUS:DEV.FUNC[@VSLOT]
e.g: 0000:00:1d:0@7
This may be important as recent changes that allow any free PCI
slot to be used for pass-through (and hotplug) may case pass-through
devices to be assigned in different locations to before. Amongst
other things, specifying the slot will allow users to move them
back, if there is a need.

Rather than use "0x0" to signify that the hotplug slot should
be automatically selected by qemu-dm, define AUTO_PHP_SLOT_STR.
At the same time, change the magic value form 0x0 to 0xff,

device to be used for hotplug.

This patch adds support for specifying the backend (tapdisk or ioemu)
to blktapctrl. Images can be specified e.g. as tap:tapdisk:aio,
tap:ioemu:qcow2 or tap:vmdk. When omitting the backend, a default is
chosen based on the image type (currently always tapdisk because ioemu
as a backend is broken until a follow-up patch series against qemu-xen
is applied)

This is a corrected version of a patch commited as c/s 19250 and
reverted by c/s 19314. Thanks to "trap sigerr ERR" in
xen-hotplug-common.sh the xen-hotplug-cleanup would exit when reading
/local/domain/ID/vm fails thus skipping all the xenstore-rm lines in
the rest of the script.
Change deviceDestroy behavior to remove /vm/UUID/device/...
path only when force was used (as it already does so for both frontend
and backend) and do the removing from xen-hotplug-cleanup script when
we are sure the device is really not attached to the guest any more.

The code was attempting to use the domain's current number of pages
(info.nr_pages) as a maximum index. We then walk the memory map and
can easily over-write past the end of the nr_pages-sized array, if the
domain has more pages mapped in than earlier (live dump). Restrict
ourselves to the current number of pages.
Also fix the dump core method in xend to actually implement the crash
and live options. In particular this means that xend clients other
than xm now get non-live dumps by default.

In the stubdom case you can now specify sdl=1 and vnc=1 (again, both
can be selected at the same time) in the vfb configuration.
So instead of:
vfb = [ 'type=vnc' ]
now you have:
vfb = [ 'vnc=1,sdl=1' ]
the former configuration option is deprecated but still supported for
backward compatibility.

D3hot state in some PCI devices causes the failure of domain
creation/destruction.
The default is "pci_power_mgmt=3D0" which disables the guest OS from
managing D-states because it would be better to avoid the trouble than

This patch adds a per-domain flag to specify whether a domain will be
S3 integrity protected when Xen is launched using tboot/TXT.
The tools now support an integer domain configuration parameter called
's3_integrity', which defaults to 1, to enable S3 integrity protection.
The struct arch_domain structure has been extended to have an
's3_integrity' field that represents this setting.

1) PCI_PM_CTRL_NO_SOFT_RESET: this is bit3 of PMCSR(Power Management
Control/Status). It should be 8. This bit means a device's capability
of not doing an internal reset across D3hot/D0.
If the bit is 1, there shall be no reset across D3hot/D0, so we should
not use it as a method to reset device.
2) When performing reset using standard FLR methods, we should sleep
at least 100ms; in current code, it's incorrect somewhere we sleep
0.2s and somewhere 0.01s.
3) In detect_dev_info(), fix a typo: PCI_EXP_TYPE_PCI_BRIDG ->
