The WEBVTT format issue was introduced in #1092 (after v0.88), so I didn't include it in the changelog. See WebVTT file structure for newline requirements.
Added the WEBVTT header to multitrack output files (mp4).
Generate multitrack filenames based on the output file instead of the input file. This fixes the situation where the -o argument is used and the first track is saved to the specified output location and the other tracks are saved next to the input file. I added char *original_filename to struct ccx_s_write, to avoid chained suffixes with three or more tracks (e.g. "test_2_3.vtt").
