The integration process that I envisioned is something like the
following:

- Add any missing options to the xen-unstable build system to avoid
cloning and building sub-components, such as qemu, seabios, etc. Many of
these configure options are already there, like --with-system-qemu and
--with-system-ovmf.

- build all these components separately in raisin

- introduce raisin in osstest

- disable by default cloning and building sub-components from xen-unstable

/ time passes /

- remove options to clone and build sub-components from xen-unstable
