Final commit for the initial modularisation pass:

- Broke part of m_scheduler off into a new module m_threadstate.  It
  contains ThreadState, VG_(threads)[] and some basic operations on the
  thread table.  All simple stuff, the complex stuff stays in m_scheduler.
  This avoids lots of circular dependencies between m_scheduler and other
  modules.

- Managed to finally remove core.h and tool.h, double hurrah!

- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
  include by every single C file.

- Lots of little cleanups and changes related to the above.

- I even did a small amount of documentation updating.
