* file.c (rb_enc_path_next, rb_enc_path_skip_prefix)
  (rb_enc_path_last_separator, rb_enc_path_end)
  (ruby_enc_find_basename, ruby_enc_find_extname): encoding-aware
  path handling functions.

* file.c (rb_home_dir, file_expand_path, rb_realpath_internal)
  (rb_file_s_basename, rb_file_dirname, rb_file_s_extname)
  (rb_file_join): should respect the encodings of arguments than
  file system encoding.  [ruby-dev:45145] [Bug #5919]

* dir.c (check_dirname, ruby_glob0): ditto.

* ext/pathname/pathname.c (path_sub_ext): ditto.

* util.c, include/ruby/util.h (ruby_add_suffix): remove the function.
  [Bug #5153] [ruby-core:38736]

* io.c (argf_next_argv): remove the call of above function.

* ext/-test-/add_suffix, test/-ext-/test_add_suffix.rb: remove the test
  extension module because this is only for testsing ruby_add_suffix().

* LEGAL: remove the mention about a part of util.c, because now we
  removed the part.

* io.c (argf_next_argv): now the new filename is not guranteed to
  use, so should check the return value of rename(2).

* test/ruby/test_argf.rb (TestArgf#test_inplace_rename_impossible):
  now we expect same result with other platforms on no_safe_rename
  platforms (=Windows).

	* include/ruby/win32.h (FD_SET): change function to macro.
	  To avoid buffer overflow when smaller FD_SETSISE is used in ext
	  libraries.

	* win32/win32.c (rb_w32_fdset): this function is not used anymore.
	  But we leave this for compatibility.

	* win32/win32.c (rb_w32_select_with_thread): fix SEGV when smaller
	  FD_SETSISE is used in ext libraries. Dereference of fd_set pointer
	  causes SEGV.

	* test/-ext-/win32/test_fd_setsize.rb(TestFdSetSize): add tests for
	  above.

	* ext/-test-/win32/fd_setsize/depend: ditto.

	* ext/-test-/win32/fd_setsize/extconf.rb: ditto.

	* ext/-test-/win32/fd_setsize/fd_setsize.c: ditto.
