In vg_memory.c, startup_segment_callback, fix initialisation ordering
problem which caused the leak checker to misbehave following recent
PLT-bypass workaround.
In short, it is an error to announce to the skin, segments found which
belong to the low-level memory manager, because the skin may then mark
them as accessible to the client. This is wrong, and the client
should only acquire accessible memory via malloc etc and stack
movement. Now we carefully avoid mentioning any segment belonging to
the low level memory manager.
Take the opportunity to improve VG_(within_m_state_static) so that it
also detects pointers within the thread table. This can reduce the
number of blocks the leak checker spuriously thinks are still
reachable.
