  Log:
    merge revision(s) 58745,58780,59040,60743: [Backport #13863]
    
    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.
