Subject: * io.c (rb_fopen): mode string copy at the lowest level.

* io.c (rb_io_flags_mode): requires output buffer no more.  no
  allocation needed.

* array.c (rb_ary_index): takes a block to compare items in an
  array.  [ruby-talk:113069] [Ruby2]

* array.c (rb_ary_rindex): ditto.

* marshal.c (r_byte): retrieve pointer from string value for each
  time.  [ruby-dev:24404]

* marshal.c (r_bytes0): ditto.

* enum.c (sort_by_i): re-entrance check added.  [ruby-dev:24399]

* io.c (io_read): should freeze all reading buffer.
  [ruby-dev:24400]
