The Intel GPU uses a two pages NVS region called OpRegion.
In order to get full support for the driver in the guest
we need to map this region.
This patch reserves 2 pages on the top of the memory in the
reserved area and mark this region as NVS in the e820. Then
we write the address to the config space (offset 0xfc) so the
device model can map the OpRegion at this address in the guest.

To acknowledge the tools' setting of control/shutdown it is normal for
PV drivers to rm the key. This leads to libxl__xs_read() returning
NULL and thus a subsequent strcmp on the return value will cause a
segfault.

I could have sworn I did this years ago.
IIRC the need for our own copy was due to the use of io_set_eventfd which is
not present in version 0.3.106. However it is in 0.3.107 the first version of
which was uploaded to Debian in June 2008 (I can't find a better reference for
the release date).
The necessary version is available in Debian Lenny onwards and is in at least
RHEL 6, Fedora 13 and OpenSuSE 11.3. The necessary version appears to not be
available in RHEL 5 or SLES 11 which is why I haven't simply nuked the in tree
version.
This is based on tools-system-libaio.diff from the Debian packaging although I
have made it optional (but default on).

Change the way we relocate the memory page if they overlap with pci
hole. Use new map space (XENMAPSPACE_gmfn_range) to move the loop
into xen.
This code usually get triggered when a device is pass through to a
guest and the PCI hole has to be extended to have enough room to map
the device BARs. The PCI hole will starts lower and it might overlap
with some RAM that has been alocated for the guest. That usually
happen if the guest has more than 4G of RAM. We have to relocate
those pages in high mem otherwise they won't be accessible.

Create two new variables called APPEND_ and PREPEND_ to add compile
flags at the beginning or at the end of the search path.
Added a new semantic for user defined compile flags, here is the list
of possible options:
PREPEND_LIB: add libraries to the search path before xen
(before xen installation folders).
PREPEND_INCLUDES: add headers to the search path before xen
(before xen installation folders).
APPEND_LIB: add libraries to the search path at the end
(after all xen installation folders have been added).
APPEND_INCLUDES: add libraries to the search path at the end
(after all xen installation folders have been added).
EXTRA_INCLUDES and EXTRA_LIB can still be used, and they will have the
same effect as PREPEND_INCLUDES and PREPEND_LIB.

grub-mkrescue internally uses xorriso, which generates a so-called
"Hybrid ISO": The ISO images also contains a DOS partition table,
which allows the identical ISO file to be stored on an USB stick for
booting from it. This breaks PyGrub, since it (wrongly) detects only
the DOS partition table and uses the first partition instead of the
complete ISO file.
Add a check to detect HybridISO files and use offset 0 in addition to
partition table parsing.
