    have __DEFINE_COMPAT_HANDLE() generate const versions
    
    Both DEFINE_XEN_GUEST_HANDLE() and __DEFINE_XEN_GUEST_HANDLE()
    each produce both const and non-const handles,
    only DEFINE_COMPAT_HANDLE() does (__DEFINE_COMPAT_HANDLE()
    does not). This patch has __DEFINE_COMPAT_HANDLE() also
    produce a const handle.
