* 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]
