PV drivers in HVM guests typically make use off an 'unplug' protocol in QEMU
to prevent co-existence of emulated devices.
See docs/misc/hvm-emulated-unplug.markdown for details.

The register of product numbers used by the blacklisting feature of this
protocol is currently directly in the xenstore.c source module of traditional
QEMU. It should really be in a Xen header file to prevent duplication/conflict
between QEMU versions.

Moreover the linux PV-on-HVM drivers make use of product number 3 seemingly
without ever registering that number.

This patch series introduces a new header and registers product number 3 for
Linux's use. A subsequent patch to qemu-xen-unstable wll be created to make
use of the new header.

Version 2:

I have re-coded at Ian Jackson's request in the form of macros that allow a
switch statement or array to be easily generated from the product list.

Version 3:

Ditching the terminator list entry.
The associated QEMU patch is unmodified by this so not resending.
