VG_(synth_fault_*), which synthesize faults as if an instruction had
caused a CPU fault. This is used in two places: one in vg_translate.c,
when trying to fetch instructions from bad memory, and the other in
vg_ldt.c, when using a bad segment register. This fixes a bug where an
assertion would fail rather than getting a useful message.

limit for file descriptors to try and prevent the target programming realising
that the reserved file descriptors exist. It also appears to fix
sysconf(_SC_OPEN_MAX) so that must be going through the same system call.

This patch adds translation tests for most of the basic x86 instructions and
fixes a few missing/broken instructions to work properly.

threads to have thread-private data which is quickly accessible via a
segment in the GDT, stored in %gs. The patch implements the relevent
syscalls (setthreadarea), and also manages switching the VCPU's segment
information at thread context-switch time. Mostly Tom Hughes' work.

Patch to improve SSE/SS2 support
This patch should implement most of the missing SSE/SSE2 opcodes. About
the only ones it doesn't do are the MASKMOVxxx ones as they are quite
horrible and involved an implicit reference to EDI so I need to think
about them a bit more.
The patch also includes a set of tests for the MMX/SSE/SSE2 opcodes to
validate that they have the same effect under valgrind as they do when
run normally. In one or two cases this wasn't actually the case even
for some of the implemented opcodes, so I fixed those as well ;-)

I added a test case and cleaned up vg_dispatch.S while I was about it.

Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

CPUID.
Also added filters to Makefiles where missing; "make regtest" was broken
within distributions created using "make dist", now fixed.

- changed deprecated INCLUDES variable to AM_CPPFLAGS
- moved the -DVG_LIBDIR definition from AM_CFLAGS into AM_CPPFLAGS
- generally neatened them up a bit -- removed old commented out stuff, fixed a
couple of other minor things
Everything works for me, hopefully it won't break things for anyone else...

If this breaks something, please mail me first instead of reverting.
Thank you.

was present from before the core/skin split, which is now dead. Means the
script is slightly simpler, and we can dispense with lots of expected
foo.stderr.hd files.
Also undid accidental change to required Automake version in main Makefile.am
from my last commit, whoops.
