rb_w32_ugetcwd: UTF-8 version getcwd

	* dir.c (rb_dir_getwd): convert from UTF-8.

	* win32/win32.c (w32_getcwd): codepage aware getcwd using
	  GetCurrentDirectoryW.
	potential memory leak

	* dir.c (rb_dir_getwd): get rid of potential memory leak.

	* util.c (ruby_getcwd): ditto.
	file.c: realpath in OS path encoding

	* dir.c (rb_dir_getwd_ospath): return cwd path in the OS path
	  encoding.

	* file.c (rb_realpath_internal): work in the OS path encoding
	load.c: cwd encoding

	* load.c (rb_get_expanded_load_path): save cwd cache in OS path
	  encoding, to get rid of unnecessary conversion and infinite
	  loading when it needs encoding conversion.
	  [ruby-dev:50221] [Bug #13863]
