Commit 26646f3 "x86/mce: translate passed-in GPA to host machine
address" and commit 4ddf474 "tools/xen-mceinj: Pass in GPA when
injecting through MSR_MCI_ADDR" forgot to consider reserved domain
ID and mistakenly add MC_MSRINJ_F_GPADDR flag for them, which in turn
causes bug reported by
http://lists.xenproject.org/archives/html/xen-devel/2016-05/msg02640.html.
This patch removes MC_MSRINK_F_GPADDR flag and checks this when injecting
to reserved domain IDs except DOMID_SELF, and treats the passed-in
address as host machine address.

libxenforeignmemory will provide a stable API and ABI for mapping
foreign domain memory (subject to appropriate privileges).
The new library exposes an interface equivalent to
xc_map_foreign_memory_bulk, which all the other
xc_map_foreign_memory_* functions (which remain in libxc) are
implemented in terms of.
Upon request (via #define XC_WANT_COMPAT_MAP_FOREIGN_API) libxenctrl
will provide a compat API for the old names. This is used by qemu-xen
and qemu-trad as well as various in tree things (which required
de-dupping various #includes in some too to get the #define before the
first).

[ ijc -- updated MINIOS_UPSTREAM_REVISION and QEMU_TRADITIONAL_REVISION ]
This patch removes the address translation in xen-mceinj which
translates the guest physical address passed-in through the argument of
'-p' to the host machine address. Instead, xen-mceinj now passes a flag
MC_MSRINJ_F_GPADDR to ask do_mca() in the hypervisor to do this
translation.

The only remaining mentions of these addresses are in COPYING files which I
haven't touched.
Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these
files be modified here and then perhaps reverted on the next sync,
since it's only 1-2 lines and obvious what is going on.

The original rule to target "distclean" in tools/Rules.mk was in effect
"make clean". It should be "make distclean".
However not all Makefiles in subdirectories have distclean target
defined. So this patch also adds a bunch of distclean targets to various
Makefiles. They only depend on clean target and don't have any actions
in most cases.
With the patch applied, following command outputs 0 results:
find tools -name 'Makefile*' -exec grep -L 'distclean' {} \+ \
| grep -v ocaml | grep -v libfsimage
Ocaml and libfsimage are known to have distclean defined in a dedicated
rules file.

More specifically:
1. replaces xenctl_cpumap with xenctl_bitmap
2. provides bitmap_to_xenctl_bitmap and the reverse;
3. re-implement cpumask_to_xenctl_bitmap with
bitmap_to_xenctl_bitmap and the reverse;
Other than #3, no functional changes. Interface only slightly
afected.
This is in preparation of introducing NUMA node-affinity maps.

The xenstore header xs.h is producing conflicts with other software[1].
xs is a too short identifier and does not matche the library. Renaming
the headers to xenstore.h and xenstore_lib.h is the easiest way to make
them easy recognizable and prevent furthe problems.
