This doesn't compile with Xen >= 4.8

Using the uint32_t variant works in the libxl driver since we have
-DLIBXL_API_VERSION=0x040400 in LIBXL_CFLAGS. I worked around the
compilation failure with LIBXL_HAVE_MEMKB_64BITS,
I can't reproduce this problem, either with 4.8 or 4.10. Even more, if I
add alternative mock with uint64_t, under #if LIBXL_HAVE_MEMKB_64BITS, I
get compile failure, because of conflicting types (with
libxl_get_free_memory_0x040700)...
Can you confirm it's really a problem, not some mismatching header
versions on your side?
Perhaps I've also made a mistake rebasing some of these patches. Can you pretty
please rebase against current master and repost a V7 (adding all the R-B)? If
you say it passes 'make check' on 4.5 and 4.10, I'll chase down any problems on
my side. Thanks!
Regards,
Jim
