b3d2c6f8b9 lavf/segment: fix DTS inconsistencies with -reset_timestamps
The DTS needs to be resynched against the segment start PTS, or the
resulting DTS may result < PTS.

4293464705 lavf/segment: do not copy codec_tag when not available
Some muxers do not allow stream if codec_tag is incompatible.

Sometimes the passed input codec's codec_tag is not compatible with the
output muxer.

Because the codec_tag field of the segment muxer cannot be set, ffmpeg.c
doesn't know how to handle these cases.

0826d8513d segment: drop global headers setting
avconv provides an option to set it externally and there isn't a way for
the outer demuxer to report the inner demuxer flag.

Solves a bad interaction between mpegts and x264, but requires
additional setting for the user.

eb447d5159 segment: Free and reinit the muxer before calling avformat_write_header
This makes sure the muxers are set up in the way they expect
with no data left around from the previous run (which could
cause various issues including memory leaks, depending on the chaine
muxer).

This fixes memory leaks with the mpegts and flv muxers. It also
makes the usage of chained muxers correct.
