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.

In particular, print the standard supported by the selected input.
Additionally, use PRIx64 everywhere when printing standards.

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