Release Candidate 8 for Xen 4.0.0 (Looks like final candidate…)

Folks,

I have now pushed tag 4.0.0-rc8 to
http://xenbits.xensource.com/xen-unstable.hg

I expect this to be the final RC and so would like lots of final pre-release testing, and will be especially selective in taking any final fix-up patches.
