Anthony Perard to co-maintain qemu

I nominate Anthony Perard as qemu-xen co-maintainer. He has been doing a
lot of QEMU work over the years and in fact he is the original author of
the Xen enablement code in upstream QEMU.

As qemu-xen co-maintainer, he could help me manage the qemu-xen trees
and promptly backport all the relevant commits from upstream QEMU.
