Prevents memleaks when the trailer is never written or when shifting the
data fails when writing the trailer.

If an audio stream is present, the Sega FILM muxer checks for its
compability with the container during init, so that the very same check
needn't be repeated during writing the trailer.
Essentially the same is true for the presence of a video stream: It has
already been checked during init. Furthermore, after the check for the
presence of a video stream succeeded, a pointer is set to point to the
video stream. Yet said pointer (which was NULL before) will be
derefenced anyway regardless of the result of the check. Coverity thus
complained about this in CID 1434155 and removing this pointless check
will also fix this issue.

This muxer does not have any private options and so does not need a
private class.

When the faststart option for the mov/mp4 muxer is used, the current
position (i.e. the size of the already written data pre-shifting) was
evaluated twice: First in an initialization and then again later,
overwriting the first value without having ever touched it. So remove
the initialization.
Also, the clone of this code in the Sega FILM muxer behaves the same and
has been treated the same.

The current code only checks when writing the trailer whether the video
format and Codec ID are actually compatible with the container. At this
point, a lot of data will already have been written (in vain, of
course), so check during the init function instead.

Up until now, the Sega FILM muxer complained if the first stream wasn't a
video stream that there is no video stream at all which is of course
nonsense. So postpone this check.

These instances are simply redundant or present because avio_flush() used to be
required before doing a seekback. That is no longer the case, aviobuf code does
the flush automatically on seek.
This only affects code which is either disabled for streaming IO contexts or
does no seekbacks after the flush, so this change should have no adverse effect
on streaming.

As per
https://web.archive.org/web/20020803104640/http://www.pcisys.net:80/~melanson/codecs/film-format.txt,
the top bit of the info1 chunk is set as 1 for inter-coded frames and 0
otherwise.
