pvfb: Split mouse and keyboard into separate devices.
This patch creates two separate input devices for keyboard and mouse
events. The reason for this is to separate them in the linux input
layer and allow them being routed different ways.
Use case: Configure the X-Server like this to get the mouse
events directly from the linux input layer, which has the major
advantage that absolute coordinates work correctly:
This makes the keyboard stop working though in case mouse and
keyboard events are coming through the same input device, at least
with older Xorg (6.9) versions.

Assign fake pci product identifiers down from 0xffff. This may help
clarify that the devices are not actually PCI. Also it reduces
probability of accidental conflict if further real PCI assignments
occur in future (0x0002, 0x0003, ... would be obvious next identifiers
to allocate).

Linux 2.6.19 (x86-64) makes use of this feature if available, but Xen
(validly) fails the attempt to write the respective MSR. Hence the
feature must be hidden from PV guests.

Break out the Python path interrogation into a separate script. This has the
advantage that the temporary path manipulation cannot affect the main script,
and that it can be shared with other programs, such as xm-test.

[LINUX] netfront: Don't call netif_carrier_off until the device is

netif_carrier_off() causes events to be queued on the device so if we
subsequently abort the allocation (e.g. due to lack of grant entries)
then we crash trying to access the now invalid device.

[XEND] Merge VFB support for PV and HVM guests.
This patch merges the way VFB are represented inside Xend by making
HVM VNC consoles use the VFB as its configuration object.
It preserves the way options are specified through xm but will create
a new VFB device that is used by image.py to put vnc config into
qemu-dm's command line. The parsing is moved into image.py's
parseDeviceModel() rather than in configVNC().
Through the Xen API, you can create a 'console' of protocol 'rfb' and
end up with a VNC console, on both HVM and PV guests. The location of
the connecting port is stored in the location attribute of the console
object. This is updated on each XendDomainInfo.update() if it
changes.
Also fixes missing read of the vnclisten and HVM_boot from the
config when initialised via xm. Makes sure bootable attribute for VBD
is store as an int when making SXP config.

[TOOLS] Fix foreign header build breakage.
Having both the Xen tree and the tools tree recurse into the foreign
headers directory causes headaches in parallel builds and when
building 32-bit tools + 64 bit Xen in the same tree.
Therefore we cause mk-symlinks to symlink in the foreign headers build
bits and generate a local version of the headers and checker tool.
Only libxc needs to do this since the other tools were actually
picking up the libxc version of the headers anyway so the mk-symlinks
calls can be removed from these components.
