added to x86-64.

Further, clean up many things to avoid needless differences to native
code, while also adding a couple of adjustments that only will be
submitted for native code inclusion, that simplify code, or that
remove unused elements.

Starting a domain with a binary kernel image fails due to an uninitialized
field. This patch fixes that problem.
The Novell NetWare port to Xen 3.0 currently uses the binary image loader.

The SVM needs the equivalent changes to the vmc.c to get this
functionality working, but this patch does not break the build.

Update the documentation to include the syntax of "hiding" a PCI
device from domain 0 and for specifying the assignment of a PCI device
to a driver domain. It also includes a brief section exploring some of
the security concerns that driver domains address and mentioning some
of those that remain.

Replace the old pciif DevController class with a new one that
configures the PCI backend. A util class detects the resource usage of
the specified PCI devices and pciif interacts with Xen to permit a
driver domain to directly access those physical I/O resources.

I also added a one-liner that causes xenbus_dev_(error|fatal) to output
to the kernel log buffer (and thus syslog) which was invaluable to me
while debugging (by default, error messages only appear in xenstore).
