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.

The structure of a ProRes frame in mov/mp4 is that of a typical atom:
First a 32 bit BE size field, then a tag detailling the content. Said
size field includes the eight bytes of the atom header.
This header is actually redundant, as the size of the atom is already
known from the containing atom. It is therefore stripped away when muxed
into Matroska and so the Matroska demuxer has to recreate upon demuxing.
But it did not account for the fact that the size field includes the
size of the header and this can lead to problems when a decoder uses the
in-band size field.

The check "if (!pb->seekable & AVIO_SEEKABLE_NORMAL)" is wrong, because
! has higher precendence than &. But it is also redundant, because this
part of the code is only ever reached when the AVIO_SEEKABLE_NORMAL flag
is set for pb. So simply remove the check.

Up until now, read_frame_internal always initialized the packet it
received. But since the recent changes to ff_read_packet, this is no
longer needed: If the parsing queue is initially empty upon entering
read_frame_internal, the packet will now either contain content upon
success or be blank upon failure of ff_read_packet. If the parsing
queue is initially not empty, the packet will be overwritten with the
oldest one from the parsing queue.
Similarly, it is unnecessary to initialize ret in read_frame_internal.
In parse_packet, it is easily possible to only initialize the packet
used as temporary storage for the output if said packet is used at all;
furthermore, this packet doesn't need to be zero-initialized, because
av_init_packet will initialize every field except size and data and
those fields will be set by av_parser_parse2.

Up until now, parse_packet() used a stack packet in case the stream is
flushed. But using such a packet is unnecessary as there is an AVPacket
readily available, it just needs to be used. Whether flushing is intended
or not will now be signalled by an explicit parameter rather than by
whether the packet parameter is NULL. This removes a few checks in
parse_packet(), gets rid of the initialization of the stack packet and
also reduces usage of sizeof(AVPacket) in libavformat.
