Remove the hook and rename native_wbinvd() to wbinvd().

Instead of having to include xenctrl.h for getting definitions of cpu
barriers, add a dedicated header for that purpose.
Switch the xen-9pfsd daemon to use the new header instead of xenctrl.h.
This is in preparation of making Xenstore independent from libxenctrl.

domctl.h and sysctl.h have an interface version, which needs to be
bumped in case of incompatible modifications of the interface.
In order to avoid misunderstandings, add a comment to both headers
specifying in which cases a bump is needed.
