c2cb01d418 lavf: introduce AVFMT_TS_NEGATIVE 
Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.

4f112a8e34 lavf/mux: add the flush_packets option. 
Note: a lot of muxers already do the flushing explicitly.

1afddbe59e avpacket: use AVBuffer to allow refcounting the packets. 
This will allow us to avoid copying the packets in many cases.

This breaks ABI.

46730e7a0c mux/chunked interleaver: better align duration chunks. 
This code causes the chunking to tend toward more optimal
alignment between streams.
The first chunks can still be less optimal aligned

1191db31c1 mux: fix chunked interleaver 
The code did not account properly for packets that where added to
the end of the packet list. Also flags for such packets where not
set correctly leading to incorrect chunked interleaving.

cae11e4031 mux: fix chunked_duration rounding anomaly 
a small value was rounded to 0 and then treated special as if
chunked_duration was 0. This led to a inconsistency that further led
to wrong interleaving

119d70db50 lavf/mux: do not pass a copy of the packet to write_packet(). 
Sometimes the muxer modifies the packet, like for instance lavf/mp3enc
changing pkt->destruct in order to keep a copy. These changes must be
kept, even though the muxer behaviour is questionable. Regression since
0072116.

Fixes #2124.

0072116ccb lavf: split packets before muxing. 
After demuxing, data and side are merged. Before decoding, they are
split. Encoder will perform with data and side split. This means that a
muxer can receive split data (after encoding) but also merged data (if
called directly after demuxing). This commit makes sure data and side
are split for the muxer.
