libxl: split forced and non-forced uses of libxl__device_del
Most forced users can now simply call libxl__device_destroy directly.
libxl__devices_destroy is something of a special case, it is really
just iterating over an opaque set of xenstore directories and removing
them. Until this can be refactored just do the force-remove case
manually, doing otherwise led to too much entanglement with the other
callers of libxl__device_destroy which do know about specific device
types.
For the time being do the same in libxl__device_pci_remove_xenstore.

libxl: separate forced and non-forced device remove.
The function libxl__device_destroy currently takes a force parameter however:
* in the forced case we initiate a graceful shutdown and then
immediately nuke the backend directory, quite likely before anyone
got a chance to react.
* the callers all have a "wait" variable and pass in "!wait" as the
force argument which is confusing since not waiting is not really
the same thing as forcing the destroy.
Therefore split the function into libxl__device_remove and
libxl__device_destroy. The former initiates a graceful shutdown which
the latter simply nukes the backend directory.
This makes some of the callers look a bit odd but that should fall out as I
continue to pull this piece of string.

hvmloader/acpi/dsdt: Fix PCI hotplug with the new qemu-xen.
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.

tools/ocaml: Rename the ocaml libraries
ocamlfind does not support namespaces, so to avoid
name clashes the module names have become longer.
Additionally, the xenstore and xenbus subdirs, which
contain several modules each, have been packed into
toplevel Xenstore and Xenbus modules.
xb becomes xenbus, xc becomes xenctrl, xl becomes xenlight,
xs becomes xenstore, eventchn becomes xeneventchn and
mmap becomes xenmmap.

passthrough: update bus2bridge mapping as PCI devices get added/removed
This deals with two limitations at once: On device removal, the
mapping did not get updated so far at all, and hotplugged devices as
well as such not discoverable by Xen's initial bus scan (including the
case where a non-zero PCI segment wasn't accessible during Xen boot,
but became accessible after Dom0 validated access information against
ACPI data) wouldn't cause updates to the mapping either.

VT-d: don't reject possibly valid DRHD or RMRR
If a non-zero PCI segment isn't accessible during Xen boot (because
firmware decided to not enter the necessary MMIO space into the E820
table), devices referred to on those segments through DRHD or RMRR
structures should not be rejected just because the devices can't be
found.
This is in line with what is being done in at least one other case
already: Systems with more than one PCI segment (usually high end
ones) are assumed to have valid firmware provided data, while systems
with just segment 0 continue to have their firmware tables validated.
