Retrofitting a stable API/ABI to the melting pot which is libxc simply
isn't going to work in practice.

IMO the most likely to succeed approach would be to split off the bits
of libxc which 3rd party's can/should/need to rely on into one of more
libraries, probably by functional area.

So far I'm aware of plans (or at least desires) to do that for:

      * Interfaces used by device-models/qemu.
      * The bits which are useful inside a guest (i.e. the
        various /dev/xen/* related helpers).

So it sounds like libxenkexec should be added to that list.
