overhaul of the thread support. Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

seem to be simply duplication of the x86 instruction set tests into
the addrcheck and helgrind trees. I'm not sure what this duplication
achieves.

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.

1. Make the output deterministic; different thread interleaving from expected
was causing failures for me.
2. Make it actually use the condition variable -- the condvar stupidly wasn't
actually being used in the expected case, because the other threads finished
all their work before pthread_cond_wait() even got called, and this prevented
the condition guarding pthread_cond_wait() from succeeding.

neater. Also remove some dodgy CFLAGS+= lines.
I had to change the expected output of pth_once.c, because the change has
altered the order of the (non-deterministic) output.

in a similar way to the previous patch that removed the limit on the
number of semaphores and fixes bug 86264.

that it is called as soon as libpthread.so is loaded even if pthread_create
is never called.
This ensures that pthread_exit will work correctly, and I think will also
cure the famous memory leak in the pthread specifics for the main thread.

handlers when a thread is cancelled which has the side effect that
programs linked with librt fail on Fedora Core 2 due to librt having
been built against the NPTL header instead of the old pthread headers.
This change extends valgrind's libpthread.so to handle both the old
and new style cleanup handlers in a similar way to NPTL and seems to
be sufficient to get programs linked with librt working again.

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.

choosing the longest symbol, choose the longest ignoring any of the libc
junk prefixes like __libc_, __, __GI_*, etc. This makes the symbol
presented to the user in messages and used in *.supp files more consistent
and comprehensible.

how autoconf/automake really work, but not me :-) What's the difference
between $(srcdir) and $(top_srcdir) (eg in coregrind/Makefile.am) ?

clearer what's wrong if you try to catch signals 32 and 33; they're not bad
signals, just used internally. Updated one regtest accordingly.

requests to allow client code to print messages through Valgrind's
logging mechanism. The new requests are:
VALGRIND_PRINTF - do a normal printf (prefixed with **PID**)
VALGRIND_PRINTF_BACKTRACE - do a printf with stack trace
VALGRIND_INTERNAL_PRINTF - printf, but for internal use (prefixed with ==PID==)
VALGRIND_INTERNAL_PRINTF_BACKTRACE - as above, with backtrace

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.

- 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...
