c/s de0f8c7c changed the use of zlib-options, and moved it from being locally
generated to coming from ./configure.
However, it neglected to modify the users of zlib-options. The curious use of
$(call ...) was to select either the -D or -l options as appropriate, but c/s
de0f8c7c broke this by loosing the `grep`.
Instead, use $(filter ...) to pick out either the -D or -l options. This
fixes the build with Clang, which complains at passing '-llzma' when trying
to compile xc_dom_bzimageloader.c to xc_dom_bzimageloader.o.

Currently __XEN_TOOLS__ is defined in the global CFLAGS used for tools
builds, exposing them all to the various unstable hypercall interfaces.
However there are places where we do not want this (in particular all
the stable libraries now under tools/libs), and there is a risk of
such uses slipping in unnoticed (currently there are none, but I
tripped over the mixed nature of the HVMOPs just now in some new code
I was putting together).
Instead only define __XEN_TOOLS__ for things which explicitly want the
unstable APIs. The vast majority of these are consumers of libxenctrl,
which have opted into unstable interfaces by using libxenctrl already,
so adding -D__XEN_TOOLS__ to CFLAGS_libxenctrl covers these without
needing to patch the dozen or so tools manually.
The libxc build itself, which doesn't use CFLAGS_libxenctrl, now needs
the define too. As does gdbsx's own low level hypercall binding
library xg.
hvmloader no longer needs to undefine the symbol.
The ocaml evtchn bindings don't actually need sysctl.h and therefore
don't actually need __XEN_TOOLS__ either.
qemu-xen-traditional doesn't use CFLAGS_libxenctrl and so we pass the
define there (via --extra-cflags) too.
Having removed __XEN_TOOLS__ replace it with
__XEN_INTERFACE_VERSION__=__XEN_LATEST_INTERFACE_VERSION__ so that in
tree code is always using the latest APIs.

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

[ ijc -- updated MINIOS_UPSTREAM_REVISION and QEMU_TRADITIONAL_REVISION ]
libxencall will provide a stable API and ABI for calling hypercalls
(although those hypercalls themselves may not have a stable API). As
well as the hypercall buffer infrastructure needed in order to safely
provide pointer arguments to hypercalls.
libxenctrl encapsulates a instance of this interface, so users of that
library are not currently subjected to any actual changes. However all
hypercalls made internally by libxc now use the correct interface. It
is expected that most users of this library will be other libraries
providing a higher level interface, rather than applications directly.
Only the basic functionality to allocate hypercall safe memory is
moved, the type safe stuff and bounce buffers remain in libxc.
Note that the functionality to map foreign pages using privcmd is not
yet moved, meaning that an xc_interface will now contain two open
privcmd file descriptors. Foreign memory mapping is logically separate
functionality and will be moved into its own library.
The new library uses a version script to ensure that only expected
symbols are exported and to version them such that ABI guarantees can
be kept in the future.

The alternative backend (a xen-api/xapi shim) is no longer around and
so this stuff is now just baggage which is getting in the way of
refactoring libxenctrl.
Nested virt probably suffices for this use case now.
This was the last component of the osdep infrastructure, so all the
dynamic loading etc stuff all falls away too.
As part of this I was forced to investigate the twisty
xc_map_foreign_* maze, which I have added to the
toolstack-library-apis doc in the hopes of doing something sensible.
NetBSD and Solaris now call xc_map_foreign_bulk_compat directly from
their xc_map_foreign_bulk, which could have been achieved by using
some ifdefs around a renamed function. This will fall out in the wash
when these functions move to their own library.

libxengnttab will provide a stable API and ABI for accessing the

All in-tree users are updated to use the new names.
Upon request (via #define XC_WANT_COMPAT_GNTTAB_API) libxenctrl will
provide a compat API for the old names. This is used by qemu-xen for
the time being. qemu-xen-traditional is updated in lockstep.
This leaves a few grant table related functions which go via privcmd
(GNTTABOP) rather than ioctls on the /dev/xen/gnt* devices in
libxenctrl. Specifically:
- xc_gnttab_get_version
- xc_gnttab_map_table_v1
- xc_gnttab_map_table_v2
- xc_gnttab_op
These functions do not appear to be needed by qemu-dm, qemu-pv

event channels.

Migration v2 changes some of this, but is similarly dependent on
