gdbsx/:
- Make use of subdir facility for the "clean" target.
- No need to remove the *.a, they aren't in this dir.
- Avoid calling "distclean" in subdirs as "distclean" targets do only
call "clean", and the "clean" also runs "clean" in subdirs.
- Avoid the need to make "gx_all.a" and "xg_all.a" in the "all"
recipe by forcing make to check for update of "xg/xg_all.a" and
"gx/gx_all.a" by having "FORCE" as prerequisite. Now, when making
"gdbsx", make will recurse even when both *.a already exist.
- List target in $(TARGETS).
gdbsx/*/:
- Fix dependency on *.h.
- Remove some dead code.
- List targets in $(TARGETS).
- Remove "build" target.
- Cleanup "clean" targets.
- remove comments about the choice of "ar" instead of "ld"
- Use "$(AR)" instead of plain "ar".

Doing so isn't appropriate here - this gets done very early in the build
process. If the directory is mean to to be buildable on its own,
different arrangements would be needed.

gdb 8.0 fixed bounds checking for 'g' packet (commit
9dc193c3be85aafa60ceff57d3b0430af607b4ce "Check for truncated
registers in process_g_packet"). This revealed that gdbsx did
not properly formatted 'g' packet - segment registers and eflags are
expected to be 32-bit fields in the response (according to
gdb/features/i386/64bit-core.xml in gdb sources). Specific error is:
Truncated register 26 in remote 'g' packet
instead of silently truncating part of register.
Additionally, it looks like segment registers of 64bit guests were never
reported correctly, because of type mismatch.

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.

0x6ae9168b: Cannot access memory at address 0x6ae9168b
Drop output of iop->remain because it most likely will be zero.
This leads to a strange message:

Add address to write error because it may be the only message

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.

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...
