I've been doing a lot of work on libxc. I've got it to the point that I'm ready to share. Below are the major changes. Feedback is greatly appreciated, especially with respect to things that would be required for it to be integrated into the xen-unstable tree.

Is there a particular reason for opening /proc/xen/privcmd on every invocation, rather than keeping a handle continuously open? Also I rather liked the xc_ name tags: the tag was a nice indication that I had reached the bottom of a tools call path and was about to hit Xen. The -errno return values are bizarre: user space has the errno variable for conveying this information.

Overall the library seems to be a greater modification of libxc than I would have thought necessary. It basically looks like a rewrite to pretty much the same interface but with names and copyrights changed.
