Recent .srt files with CR only were found in the wild.

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.

I found a bunch of (recent) SRT files in the wild with 3 to 10 line
breaks at the beginning.

Some fields of the frame are changed to reflect encoder decissions like
if its a keyframe. It thus cannot be constant.
