b8fa374fb6 lavf/concatdec: remove unrelated change during codecpar merge. 
Clearing the extradata is not related to the codecpar change,
and it breaks if auto_convert is disabled.

Fix trac ticket #5461.

3ab25e4574 Revert "lavf/concatdec: define "ffcat" and "ffconcat" extensions" 
This reverts commit 6cc12353a8.

Conflicts:
	libavformat/version.h

Allowing to automatically select the concat demuxer raises
security concerns, as it allows a possibly hostile file to
access any file on the system. Guessing the format based on
the file name extension does not allow to enable the safe
mode designed to avoid it.
