c5d0d4a965 Fix problems to do with make dist/make distcheck not finding the source 
file vg_libpthread.so.0.c.  Now:

* libpthread.so is built as just-another-so, like valgrind.so and
  valgrinq.so.

* there is a new dummy target libpthread.so.0 which is build just
  by a symlink.

Unfortunately for some reason, when the .so.0 is installed, it gets
a complete copy rather than just the symlink being copied.  But it
works, at least.

4248ca0b0a Cleanup of the dispatch mechanism. Now syscall returns and the final 
request to shutdown valgrind are done with the client request
mechanism too.  This is much better than having to check all
call/return addresses.

7a36f60133 Mega-merge of my last 2 weeks hacking. This basically does the groundwork 
for pthread_* support.  Major changes:

* Valgrind now contains a (skeletal!) user-space pthreads
  implementation.  The exciting bits are in new file vg_scheduler.c.
  This contains thread management and scheduling, including nasty crud
  to do with making some syscalls (read,write,nanosleep) nonblocking.
  Also implementation of pthread_ functions: create join
  mutex_{create,destroy,lock,unlock} and cancel.

* As a side effect of the above, major improvements to signal handling
  and to the client-request machinery.  This is now used to intercept
  malloc/free etc too; the hacky way this is done before is gone.
  Another side effect is that vg_dispatch.S is greatly simplified.
  Also, the horrible hacks to do with delivering signals to threads
  blocked in syscalls are gone, since the new mechanisms cover this case
  easily.

wrong program behaviour.  This will only have happened to people using
P6/P7/K7 class CPUs.
