Все версии в порядке выхода.

`R0.16`
- Removed a long-pending limitation that f_getcwd and double-dot ".." in the path name did not work on the exFAT volume.
- Fixed f_readdir cannot detect end of directory and it leads the application process into infinite loop. (appeared at R0.15b)
- Fixed dot names with terminating separator or duplicated separator are rejected when LFN is not enabled.
