    avformat/subtitles: add a next line jumper and use it. · 90fc00a6
    Clément Bœsch authored
    This fixes a bunch of possible overread in avformat with the idiom p +=
    strcspn(p, "\n") + 1 (strcspn() can focus on the trailing '\0' if no
    '\n' is found, so the +1 leads to an overread).
    
    Note on lavf/matroskaenc: no extra subtitles.o Makefile dependency is
    added because only the header is required for ff_subtitles_next_line().
    
    Note on lavf/mpsubdec: code gets slightly complex to avoid an infinite
    loop in the probing since there is no more forced increment.
