Various enhancements:
* Make the error message system more thread-aware.
* Fix stupid bug in do_pthread_create causing incorrect initial
%ESP values sometimes.
* Fix various other minor things needed to make opera work.
Performance of threaded apps is pretty terrible. This needs
looking into.

we'd better annotate them as such!
Fixes a floating-point misbehaviour bug reported by Robert W. Anderson

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.

--check-addrVs=no. The default behaviour, =yes, is the original
behaviour. So far this is undocumented.

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.
