merges r21492 and r21495 from trunk into ruby_1_9_1.

	* io.c (rb_io_close_read): call rb_io_fptr_cleanup() instead of
	  fptr_finalize() because the fptr has special finalizser if it is a
	  pipe.  [ruby-dev:37757] (3)

	* io.c (io_reopen, rb_io_init_copy): should register fptr to
	  pipe_list when copying pipe fptr.
