computation) into the generic core, because it's needed by the dispatch
loop of all archs. Also renamed it VG_(instr_ptr_offset), which is
clearer. Since it was the last use of the VGOFF_ prefix, I removed that
prefix.
Also cleaned up the ARM stubs slightly, by removing some of the copied,
commented-out x86 code which has since fallen out of date with the real
x86 code and was thus misleading.

- Added include/x86/: contains tool_arch.h, Makefile.am, .cvsignore.
- Added coregrind/x86/state.c. Contains some arch-specific code for dealing
with x86 registers -- eg. setting up the baseBlock, loading/saving the whole
register state. It is compiled into coregrind/x86/libarch.a and linked via
${VG_ARCH} with the core.
Relatedly, also added coregrind/x86/{core_arch.h,core_arch_asm.h}.
- Correspondingly abstracted the register state out of ThreadState. This
affected every place that touches registers, and there are a lot of them.
(Eventually all the register touching should be abstracted out in an
arch-neutral way, but not yet; one step at a time.)
- Added some declarations about register loading/saving functions to core.h;
all architectures will have to provide these functions.
- Rejigged the build system so that the arch-specific stuff is all done via
${VG_ARCH}, rather than naming e.g. x86/ directly. Appropriate -I arguments
are used so that all the headers are found, etc.

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.

with the aim of making it more robust, more correct and perhaps faster.
This patch removes the need to poll blocking syscalls, by adding a proxy
LWP for each application thread. This LWP is a kernel thread whose job
is to run all (potentially) blocking syscalls, and also to handle signals.
This allows the kernel to do more of the work of dealing with signals,
so on kernels which do this properly (2.6), Valgrind's behavious is a
lot more posix compliant. On base 2.4 kernels, we emulate some of the
missing 2.6 functionality.
