tools/libxc: untangle libxenctrl from libxenguest
Sources of libxenctrl and libxenguest are completely entangled. In
practice libxenguest is a user of libxenctrl, so don't let any source
libxenctrl include xg_private.h.
This can be achieved by moving all definitions used by libxenctrl from
xg_private.h to xc_private.h.
Export xenctrl_dom.h as it will now be included by other public
headers.
