All calls to VG_(unknown_SP_update) were recording an execontext
of one IP, useful only for track origin.
This patch implements splits VG_(unknown_SP_update)
in two different functions VG_(unknown_SP_update_w_ECU)
(doing origin tracking) and VG_(unknown_SP_update) (not doing origin tracking).

support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.
This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output. This
will be fixed.
The core-tool interface is slightly changed. The version number for
the interface needs to be incremented.

the new thread's stack, then make the stack unwinder use that information
to make a better guess at the stack bounds.
This helps avoid crashes trying to unwind the stack under wine when
the starting point is a routine without a proper stack frame.

m_stacks, because it's a nicely distinct and stand-alone piece of
functionality. This happily removes m_aspacemgr's dependence on
m_mallocfree (there was an apparent dependence due to the #include, even if
it didn't manifest itself in practice -- very important!) and m_options (not
so important).
