-g/c usbd_init()/usbd_finish() which don't do anything useful

Browse Source 
-use <fs/unicode.h> for utf16->utf8 conversion instead of a private
 implementation
-streamline the COMPAT_30 utf16->ascii conversion a bit: remove
 length check (USB_MAX_STRING_LEN is too large to be useful) and
 replace array index arithmetics
