- Update the xml1 .exp files accordingly (getting rid of one which is no
longer necessary).
- Update origin4-many.stderr.exp accordingly.
- Update the handling of scalar_exit_group accordingly.

--enable-only32bit builds on my Ubuntu box:
- For all tests, replace all operator new/new[]/delete/delete[] variants
with a common form, eg. "...operator new...". This makes
exp-ptrcheck/tests/ccc and memcheck/tests/mismatches pass.
- For Helgrind tests, replace all libpthread paths with "/...libpthread...",
as is done for libc paths. This avoids problems when /lib32/libpthread.so
is the path. No extra tests pass, but many of them get a lot closer to
passing.

- It heavily refactors the code: uses better names for things, splits up
complex functions that behaved very differently depending on how they were
called, removes some redundancies, and generally makes it much simpler and
easier to follow.
- It adds lots of comments, both inline, and also a big explanatory one at
the top which makes it clear exactly how the leak checker works and also
exactly what is meant by definite, possible, and indirect leaks. It also
has some ideas for future improvements.
- All tabs have been converted to spaces.
It also improves the functionality:
- Previously if you did --leak-check=summary, indirect and suppressed
blocks were counted as definite leaks. Now they are done properly, and so
the summary results from --leak-check=summary match those from
--leak-check=yes.
- Previously, some possibly reachable blocks were miscategorised as
definitely reachable, because only the pointer to the block itself was
considered, not any preceding pointers in the chain. This is now fixed.
- Added memcheck/tests/leak-cases, which fully tests all the possible
combinations of directly/indirectly reachable and possibly/definitely
reachable.
And it improves the manual quite a bit, and the FAQ a little bit.
This doesn't fix the leak checker to handle MALLOCLIKE_BLOCK works that have
been taken from within malloc'd blocks, but I think I know how to do it and
hope to do so in a subsequent commit.
It also changes all instances of "<constant>memcheck</constant>" in the
Memcheck manual to "Memcheck", for consistency and because "Memcheck" is
easier to write. There's one similar case for DRD but I didn't change that.

longer valid, as the comment indicates. Furthermore it mmaps arbitrary bits
of address space and so is horribly unportable, and doesn't work on Darwin.

- Rename 'oset_test' as 'unit_oset' to make its meaning more clear.
- Remove VG_(atoll36), VG_(strtoll8)() and VG_(strtoll36)(); they're not
used and so untested, but easy to crib from similar functions if they need
to be added again later.

- Created Makefile.tool-tests.am, put standard AM_CFLAGS et al for tests in
it.
- A number of tests are shared between Helgrind and DRD. They used to be
built in both directories. Now they are only built in helgrind/tests/,
and the DRD .vgtest files just point to the executable in helgrind/tests/.
Most of these (about 30) had the source files in helgrind/tests/; I moved
the three that were in drd/tests/ into helgrind/tests/ for consistency.
- Fixed rwlock_test, which was failing to run due to a wrong name in the
.vgtest file.
- Removed remnants of unused 'hello' test for Memcheck.
- Avoided redundant flag specification in various places, esp.
memcheck/tests/Makefile.am.
- Removed unnecessary _AIX guards in some Linux-only tests.

I changed it to just filter the entire stack trace out for these errors (both
normal and XML cases). The syscall name is still present in the error
string. This allows a one or more alternative expected output files to be
removed for several tests, which is A Very Good Thing.
Also, I killed filter_test_paths because it was weird and clumsy and the
above change obviated most of its use and the remaining effects could be
achieved in other ways.
Also, I fixed up the scalar* tests a little and they now pass on my machine,
(and hopefully at least some other machines) for the first time ever!

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.

the DARWIN branch easier later.
- Remove the disabled vgtest_ume test, it's very unlikely it'll ever work
again.
- Move VG_(find_auxv) to initimg-linux.c, the only place it's used, and make
it static.

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.

memcheck/tests/Makefile.am and was copied into drd/tests/Makefile.am.
When building regtests for a 32-bit only build on a 64-bit CPU, the
use of $(VG_ARCH) in these Makefiles is incorrect, because VG_ARCH
will be set to the 64-bit architecture, not the 32-bit architecture.
See comments on VG_ARCH_PRI and VG_ARCH_MAX in configure.in for more
details.

support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.
This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output. This
will be fixed.
The core-tool interface is slightly changed. The version number for
the interface needs to be incremented.

--fill-free=<hexnumber>, which cause malloc'd(etc) and free'd(etc)
blocks to be filled with the specified value. This can apparently be
useful for shaking out hard-to-track-down memory corruption. The
definedness/addressability of said areas is not affected -- only the
contents. Documentation to follow.

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.
