we'd better annotate them as such!

request to shutdown valgrind are done with the client request
mechanism too. This is much better than having to check all
call/return addresses.

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.

UInstrs accordingly. Fixes a bug in the simulated CPU in which the
results of f{u}comi{p} FPU insns were ignored, potentially leading to
wrong program behaviour. This will only have happened to people using
P6/P7/K7 class CPUs.
