VEX, and clean up the rest of it and push it into
coregrind/x86/state.c. coregrind/x86-linux/ldt.c is now empty, but I
see that some of the stuff in x86/state.c should really be in
x86-linux/ldt.c.

string in valgrind.pc.in, so that they describe Valgrind as a "dynamic
binary instrumentation framework", and don't mention platforms at all.
I had to tweak the regtest filters a bit for this.

arch-neutral ones like R_STACK_PTR). Where they were used, we now always talk
about an offset into the Vex guest state, and an offset. As a result,
the shadow register get/set functions had to change. They now also use
an offset and size, and in an arch-neutral way.
Also, I combined the five the post_reg_write* functions into a single one that
takes a 'CorePart' parameter (plus also a ThreadId). Also, I added more
arguments (the CorePart, and the ThreadId) to the post_mem_write event, for
consistency with the pre_mem_* events.
Also, I reduced the number of register names that must be specified by each
arch, by factoring out duplication; and shortened their names for the core (eg.
ARCH_STACK_PTR is now STACK_PTR).
Plus some related minor cleanups in syscall wrappers.

state pointer points directly at the ThreadState.arch.vex field, thus
updating it in place and avoiding a lot of code (and time-wasting)
which copies stuff back and forth to baseBlock.
Fix zillions of other places in the system where the current thread id
is needed. It is now passed to all needed places.

socketcall() and ipc() which are done too simplistically.
Also, VG_([gs]et_thread_area)() both now return -VKI_EFAULT if they are given a
NULL pointer.

- Added include/x86-linux/ and include/linux/ subdirectories, with Makefile.am
files.
- Overhauled the definitions of kernel types. include/vg_kerneliface.h is now
three files, include/linux/vki.h, include/x86-linux/vki_arch.h, and
include/x86-linux/vki_arch_posixtypes.h. These files separate the
common/Linux and x86/Linux parts cleanly. All code is copied verbatim from
the relevant kernel headers, except that VKI_/vki_ prefixes are added as
necessary to distinguish them from glibc types. (This is done consistently,
unlike previously when some types did not have the prefixes.)
All code is clearly marked to show which particular header file it came from,
and the Linux version used. (I used 2.6.8.1, the most recent stable release,
for all of them.)
A few of the types changed; this is because they changed between the older
versions of Linux and the current 2.6.8.1. I checked that all these changes
were ok with respect to backwards compatibility for our purposes.
- vg_unsafe.h has been removed; we are no longer including any kernel headers,
as we have our own copies for everything. This is because installed kernel
headers are not reliable, and often cause compilation problems. (bug
#92420 is a recent example)
- Removed some no-longer-needed header-presence tests from configure.in.
- Some code in the rest of Valgrind was changed to account for some slight
changes in the names of our VKI_/vki_ kernel constants and types.
- Updated README_MISSING_SYSCALL_OR_IOCTL accordingly.
- Fixed off-by-one error with VKI_GDT_ENTRY_TLS_MAX (merged from stable branch)
The end result is that the kernel types situation should be much clearer, and
similar files can be created relatively easily for other architectures as
necessary.

- move LDT stuff out of core, into x86-linux specific stuff. Some of it
(VG_(do_useseg)()?) may be really x86-specific, rather than
x86/linux-specific, but that can be fixed later if it's really shared with
another OS.
