* safe.c (rb_set_safe_level, safe_setter): raise an ArgumentError

  when $SAFE is set to 4.  $SAFE=4 is now obsolete.
  [ruby-core:55222] [Feature #8468]

* object.c (rb_obj_untrusted, rb_obj_untrust, rb_obj_trust):
  Kernel#untrusted?, untrust, and trust are now deprecated.
  Their behavior is same as tainted?, taint, and untaint,
  respectively.

* include/ruby/ruby.h (OBJ_UNTRUSTED, OBJ_UNTRUST): OBJ_UNTRUSTED()
  and OBJ_UNTRUST() are aliases of OBJ_TAINTED() and OBJ_TAINT(),
  respectively.
