* io.c (read_all): block string buffer modification during

  rb_io_fread() by freezing it temporarily. [ruby-dev:24479]

* dir.c (rb_push_glob): block call at once the end of method.
  [ruby-dev:24487]

* ext/enumerator/enumerator.c (enum_each_slice): remove
  rb_gc_force_recycle() to prevent potential SEGV.
  [ruby-dev:24499]

* ext/zlib/zlib.c (zstream_expand_buffer): hide internal string
  buffer by clearing klass.  [ruby-dev:24510]

* ext/socket/socket.c (sock_s_getservbyaname): protocol string
  might be altered.  [ruby-dev:24503]

* string.c (rb_str_upto): check if return value from succ is a
  string.  [ruby-dev:24504]

* io.c (rb_io_popen): get mode string via rb_io_flags_mode() to
  avoid mode string modification.  [ruby-dev:24454]

* io.c (rb_io_getline_fast): should take delim as unsigned char to
  distinguish EOF and '\377'.  [ruby-dev:24460]

* io.c (rb_io_getline): add check for RS modification.
  [ruby-dev:24461]

* enum.c (enum_sort_by): use qsort() directly instead using
  rb_iterate().  [ruby-dev:24462]

* enum.c (enum_each_with_index): remove rb_gc_force_recycle() to
  prevent access to recycled object (via continuation for
  example).  [ruby-dev:24463]
