Despite the doxy stating that it's called when the muxer is destroyed,
this was not true in practice. It's only called by av_write_trailer()
and on init() failure.
An AVFormatContext may be closed without writing the trailer if errors
ocurred while muxing packets, so in order to prevent memory leaks, it
should effectively be called when freeing the muxer.

If there is an error in mpeg_mux_init() (the write_header function of
the various MPEG-PS muxers), two things might happen:
1. Several fifos might leak. Instead of freeing them, the goto fail part
of the functions freed the private data of the AVStreams instead,
although this will be freed later in free_stream() anyway.
2. And if the function is exited via goto fail, it automatically
returned AVERROR(ENOMEM), although this is also used when the error is
not a memory allocation failure.
Both of these issues happened in ticket #8284 and have been fixed.

The pointer fp after the call to chromaprint_get_raw_fingerpoint() points to an array
of uint32_t whereas the current code assumed just a char stream. Thus when writing the
raw fingerprint, the output would be truncated by a factor of 4.
For reference the declaration of the function from chromaprint.h is:
int chromaprint_get_raw_fingerprint(ChromaprintContext *ctx, uint32_t **fingerprint, int *size);
Allows the creation of the sdtp atom while remuxing MP4 to MP4. This
atom is required by Apple devices (iPhone, Apple TV) in order to accept
2160p medias.
Not only the first, but each latest chunk must be cached to allow
seekback after finding the mime boundary.

According to RFC1341, the multipart boundary indicated by the
Content-Type header must be prepended by CRLF + "--", and followed
by CRLF. In the case of strict MIME header boundary handling, the
"--" was forgotten to add.
Fixes trac #7921.
A side effect is that this coincidentally breaks enforcement of
strict MIME headers against servers running motion < 3.4.1, where
the boundary announcement in the HTTP headers incorrectly used the
prefix "--", which exactly matched this bug's behavior.
