The number of sets, ie. number of cache lines divided by associativity,

This change is needed for default cache parameters used on some Intel
Core 2 and Atom processors.

clearer what they mean:
- They all have VGCONF_ prefixes now, to indicate they come out of
configure.in (and are clearly distinguished from the VGA_/VGO_/VGP_
#defines passed in to C files).
- The ones that refer to the primary *or* secondary platform have _INCLUDES_
in them.
- The ones that are in all-caps have a _CAPS suffix.
So, for example, what was VGP_X86_LINUX is now
VGCONF_PLATFORMS_INCLUDE_X86_LINUX, which is more verbose but also a lot
clearer. The names of the #defines used in the C files (VGA_x86, VGO_linux,
etc) are unchanged.
cputest.c: changed to reflect the Valgrind installation's capabilities,
rather than the machine's capabilities. In particular, if
--enable-only32bit is used on a 64-bit machine, then this program will claim
to only support 32-bits. Also use the VGA/VGO/VGP macros which are clearer
than the __i386__ ones. (This is partially merged from the DARWIN branch.)
configure.in: clean up the comments, distinguish different sections more
clearly, and generally make it more readable.
valgrind.pc.in: try to make this more accurate. I doubt anyone's using it.
It doesn't appear to be set up to handle dual-architecture builds.

arch/OS/platform-specific tool test dirs, instead writing it by hand.
This is important because up until now if we had any arch-specific test
dirs, we needed such dirs for all archs. Now that we also have
OS-specific and platform-specific test dirs, we don't want to have
(mostly) empty dirs for every arch/OS/platform.
- Correspondingly, removed several empty directories under memcheck/tests/
and cachegrind/tests that are no longer needed.
- Also removed VG_ARCH_ALL from configure.in.
- Also used an arch-specific guard rather than a platform-specific one where
appropriate in cachegrind/tests/Makefile.am.

vcpu_bz2.c was (I think) an "svn copy" of perf/bz2.c. Because it's a
copy, the two can get out of sync, which was a problem with Greg
Parker's Darwin patch. So we remove vcpu_bz2.c, and make
vcpu_bz2.vgtest invoke perf/bz2 directly.

wrap5.c was likewise an "svn copy" of memcheck/tests/wrap5.c, so we do
the equivalent thing with it.

Josef, I think Callgrind does not have this bug, but you might want to say

somewhat to move less relevant material out of the way to some extent.
The main changes are:
* Update date and version info
* Mention other tools in the quick-start guide
* Document --child-silent-after-fork
* Rearrange order of sections in the Valgrind Core chapter, to move
advanced stuff (client requests) to the end, and compact stuff
relevant to the majority of users towards the front
* Move MPI debugging stuff from the Core manual (a nonsensical place
for it) to the Memcheck chapter
* Update the manual's introductory chapter a bit
* Connect up new tech docs summary page, and disconnect old and
very out of date valgrind/memcheck tech docs
* Add section tags to the Cachegrind manual, to stop xsltproc
complaining about their absence

VG_(record_startup_wd) which records the working directory at startup,
and VG_(get_startup_wd) which later tells you what value was recorded.
This works because all uses of VG_(getcwd) serve only to record the
directory at process start anyway. The motivation is that AIX does
not support sys_getcwd directly, so it's easier for the launcher to
ship in the required value using an environment variable. On Linux
sys_getcwd is used as before.

--branch-sim=yes is specified, Cachegrind simulates a simple indirect
branch predictor and a conditional branch predictor. The latter
considers both the branch instruction's address and the behaviour of
the last few conditional branches. Return stack prediction is not
modelled.
The new counted events are: conditional branches (Bc), mispredicted
conditional branches (Bcm), indirect branches (Bi) and mispredicted
indirect branches (Bim). Postprocessing tools (cg_annotate, cg_merge)
handle the new events as you would expect. Note that branch
simulation is not enabled by default as it gives a 20%-25% slowdown,
so you need to ask for it explicitly using --branch-sim=yes.

basename to be something other than "cachegrind.out".
* Observe the core-supplied --log-file-qualifier, if specified,
in creation of output file names.
* To make the above work, move most of the stuff in cg_pre_clo_init
into cg_post_clo_init, so that the core's determination of the
log file qualifier, if any, is done by the time cachegrind comes
to process its arguments.

Cachegrind docs.
Removed the Cachegrind tech docs, because they're so out of date to be
useless. My PhD dissertation gives a much better description of how
Cachegrind works. (I mentioned this in the Cachegrind user manual.) The
only still-useful part of Cachegrind's tech docs, the output file format
description, I moved into the Cachegrind user manual.

Makefile.am changes for AIX5. Almost all boilerplate stuff fitting in
with the existing factorisation scheme. The only change of interest
is that configure.in now generates automake symbols of name
VGP_platform and VGO_os, whereas previously it just made VG_platform
which was a bit inconsistent with the VGP/VGO/VGA scheme used in C
code.

interface, except for the syscall numbers, into that. Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.
include/pub_tool_basics.h previously dragged in the entire kernel
interface. I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly. This is why there are many modified .c files -- they have
all acquired an extra #include line.
This certainly breaks all platforms except x86. Will fix shortly.
