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.

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.

Added autotools magic to replace custom check scripts. The previous
checks have been ported to autoconf, and some additional ones have
been added (plus the suggestions from running autoscan). Two files are
created as a result from executing configure script, config/Tools.mk
and config.h.
conf/Tools.mk is included by tools/Rules.mk, and contains most of the
options previously defined in .config, that can now be set passing
parameters or defining environment variables when executing configure
script.
config.h is only used by libxl/xl to detect yajl_version.h.
[ tools/config.sub and config.guess copied from
autotools-dev 20100122.1 from Debian squeeze i386,
which is GPLv2.
tools/configure generated using the included ./autogen.sh
which ran autoconf 2.67-2 from Debian squeeze i386. autoconf
is GPLv3+ but has a special exception for the autoconf output;
this exception applies to us and exempts us from complying
with GPLv3+ for configure, which is good as Xen is GPL2 only.

It's not needed unless you are including headers in the current
directory _and_ you can't use "" instead of <> because the headers are
to be installed.

Several places include it in CFLAGS even though it is never defined. A
few others use it as nothing more than a gathering point for
CFLAGS. Get rid of it.

Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

gdbsx hacks CFLAGS to remove optimisations for easier debugging, however
this breaks dep generation due to an early evaluation of CFLAGS and
leaves stale files called "..d" after a make clean. We could possibly
fix this by separating dep generation from the rest of CFLAGS but it
seems a little invasive. The gdbsx hackers can do their own thing during
development and testing anyway...
