    Rename scm_i_thread to scm_thread
    
    * libguile/scm.h (struct scm_thread, scm_thread): Rename from
      scm_i_thread.
    * libguile/deprecated.h (scm_i_thread): Add deprecated typedef.
    * libguile/threads.h: Adapt to renaming.
    * libguile/intrinsics.h:
    * libguile/scmsigs.h:
    * libguile/cache-internal.h: Remove threads.h includes; unnecessary with
      the forward decl.
    * libguile/continuations.h:
    * libguile/gc-inline.h:
    * libguile/async.h: Adapt scm_thread type name change.
    * libguile/async.c:
    * libguile/continuations.c:
    * libguile/control.c:
    * libguile/dynstack.c:
    * libguile/dynwind.c:
    * libguile/eval.c:
    * libguile/finalizers.c:
    * libguile/fluids.c:

    * libguile/threads.c:
    * libguile/throw.c:
    * libguile/vm-engine.c:
