Some subtitling formats, namely AQT and Subrip09, define the end of a
subtitle as the beginning of the following. Since currently we read one
subtitle at time, for these format we keep two global *subtitle,
previous_aqt_sub and previous_subrip09_sub, pointing to previous subtitle,
so we can change its end when we read current subtitle starting time.
When USE_SORTSUB is defined, we use a single global unsigned long,
previous_sub_end, for both (and even future) formats, to store the end of
the previous sub: it is initialized to 0 in sub_read_file and eventually
modified by sub_read_aqt_line or sub_read_subrip09_line.
