Add keyframe index metadata
Used to facilitate seeking; particularly for HTTP pseudo streaming.
 1. read live streaming or file by sequence
 2. if use add_keyframe_index option, add a mark flag at the position,
    use to insert new context at the last step.
 3. add the keyframes *offset* and *timestamp* into a list
 4. if use add_keyframe_index option, shift the metadata data from
    mark flag offset
 5. insert the keyframes *offset* and *timestamp* from the list by
    sequence
 6. free the list
 7. end.

Add FATE test case;

This allows a subsequent change to compress directly into the output packet when possible.

If the value is negative then it means padding at the start of the packet
instead of at the end.

Commit 04964ac3 ("avformat/hls: Fix missing streams in some
cases with MPEG TS") caused a regression where subdemuxer streams that
use probing (e.g. dts/eac3/mp2 in mpegts) no longer get probed properly.

This is because the codec parameters from the subdemuxer stream, once
probed, are not passed on to the main stream.

Fix that by updating the codec parameters if the codec id changes.
