This introduces a thread-state object and moves various C globals

there.  It also introduces #defines for these globals to avoid a
monster patch.

The #defines mean that this patch also has to rename a few fields
whose names clash with the defines.

There is currently just a single "thread"; so this patch does not
impact Emacs behavior in any significant way.
