The d_name member of struct dirent should be a pointer

Rework for 6095070, so then any encoding is supported. The path
segment length is measured in wchar_t size, whereby the number
of wchar_t is 255+\0. This means, in the actual encoding, the path
segment size can become (255*<bytes per glyph>)+\0 bytes in worst
case. It is still valid, as all the FS API uses wide chars
internally.
