22-mutex-destroy-unlock:
It seems that glibc assumes in its internal use of pthreads that
destroying a lock implicity unlocks it. This patch handles this case
so that lock ownership tracking is accurate.
Also handles the case of the dyanmic linker wanting to do locking
before Valgrind has started up. vg_libpthread now implements toy
lock/unlock functions to keep it happy and leave the locks in a
sensible state. Implements some untested code to handle the case where
a lock is taken before Valgrind is running but released afterwards.

03a-open-nonblock
Implement open of FIFOs for threaded programs, so that everything
doesn't block when we try to open a FIFO file in a non-blocking way.

all commentary from our libpthread.so through to the valgrind core and
hence to the selected logging sink.

16-function-intercept
Implement a more reliable for vg_libpthread to intercept libc
calls. Since the only reliable way of making sure that our code
defines the symbol is by making sure that valgrind.so itself does it,
this patch adds a new file, vg_intercept.so, which defines those
symbols. They are then passed off to a weak local function if
libpthread isn't present, or to the libpthread version if it is.

the appearance of libc_internal_tsd_address requires a redesign, since
the existing scheme doesn't make it sensible to take the address of a
specific-data value.
New scheme is that the ThreadState structure carries not the table of
specifics, but merely a pointer to such. This is allocated from the
client-side library, thus residing in client-visible memory and so
addresses can validlyh be taken.

- autoconf stuff for detecting glibc-2.3
- vg_libpthread_unimp.c: hack for __pthread_clock_[gs]ettime
- vg_libpthread.c: initialise thread's default locale by calling
__uselocale(LC_GLOBAL_LOCALE) at the right time. Gruesome.
Also need to do this for new other threads - not yet done.
- cleanups -- don't use write() to write messages when bombing out,
instead go direct to the syscalls. Avoids nasty circularities
with glibc initialisations.

exposed by scheduling changes caused by commit vg_scheduler.c rev 1.70.
We cannot simply pass the __attr pointer to the child, since it could
point to stuff on the parent's stack, which might not exist by the time
the child looked at it. Prior to scheduler.c rev 1.70 the child would
have been scheduled as soon as created, so the access was made before the
parent could clear the stuff from its stack. From rev 1.70 and after
the parent continues after creating the child, causing invalid stack
accesses when the child finally runs.

nonblocking select() implementation, notice this and correspondingly return
with EINTR. This appears to fix the MySQL hang-at-exit problem.

Now at least valgrind doesn't crash/assert. Still doesn't work tho.
