Both date_time_t and timestamp_t were used in memory only, but
date_time_t had the additional MilliSecond field. To keep the
functionality I added the millisec field to timestamp_t and
replaced all usages of date_time_t with timestamp_t.

For storing on disk the values from timestamp_t get shifted
and combined (exfat_set_entry_time).
