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.

a854362b40 segment: Flush buffered data before finishing a segment

f7b240434c segment: Set the resend_headers flag for each segment
This makes sure new inline headers are emitted when the next
packet is written. This allows segmenting mpegts without calling
write_header/write_trailer (nor freeing/reiniting the muxer)
for each segment.

378a6315b7 segment: Add an option for disabling writing of a header/trailer to each segment
Some segmented formats (such as fragmented mp4) are "bare", as in,
the segment files do not have the same headers/trailers as full normal
files of that format have.

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.

73871dc96f segment: Use the public av_write_header/av_write_trailer functions
With this change, the segmenter muxer doesn't rely on anything
not available/supported to libavformat external users, making
the segmenter muxer do things just like a normal segmenter
application using libavformat would do.

0edae4e628 segment: Properly create new AVStreams for the chained muxer
Before, the chained muxer reused the AVStreams array from
the outer muxer, which made it impossible to use the proper
public functions (such as av_write_frame) when calling the
chained muxer.
