This reverts commit cea7c19cda0ea1630ae1de8c102ab14231b9db10.
Until an API is added to make index_entries public in a proper way, keeping
this here is harmless.
Commit 6973df112275c8ea4af0bf3cb1338baecc1d06b3 added support
for music tracks by outputting its two containing tracks
together in one packet. But the actual data is not contiguous
in the file and therefore one can't simply use av_get_packet()
(which has been used before) for it. Therefore the packet was
now allocated via av_new_packet() and read via avio_read();
and this is also for non-music files.
This causes problems because one can now longer rely on things
done automatically by av_get_packet(): It automatically freed
the packet in case of errors; this lead to memleaks in several
FATE-tests covering this demuxer. Furthermore, in case the data
read is less than the data desired, the returned packet was not
zero-allocated (the packet's padding was uninitialized);
for music files the actual data could even be uninitialized.
The former problems are fixed by using av_get_packet() for
non-music files; the latter problem is handled by erroring out
unless both tracks could be fully read.

When extended atom size support was added to probing in
fec4a2d232d7ebf6d1084fb568d4d84844f25abc, the buffer
size check was backwards, but probing continued to work
because there was no minimum size check yet, so despite
size being 1 on these atoms, and failing to read the 64-bit
size, the tag was still correctly read.
When 0b78016b2d7c36b32d07669c0c86bc4b4225ec98 introduced a
minimum size check, this exposed the bug, and broke probing
any files with extended atom sizes, such as entirely valid
large files that start whith mdat atoms.

Add the "http_proxy" option and its handling to the "tls" protocol,
pass the option from the "https" protocol.
The "https" protocol already defines the "http_proxy" command line
option, like the "http" protocol does. The "http" protocol properly
honors that command line option in addition to the environment
variable. The "https" protocol doesn't, because the proxy is
evaluated in the underlying "tls" protocol, which doesn't have this
option, and thus only handles the environment variable, which it
has access to.
Fixes#7223.

64 bits are needed in order to retain the uid values of Matroska
chapters; the type is kept signed because the semantics of NUT chapters
depend upon whether the id is > 0 or < 0.

Up until now, there has been no check that each chapter has a unique id;
there was only a check for whether a chapter id is zero (this happens
often when the chapters originated from a format that lacks the concept
of chapter id and simply counts from zero) which is invalid in Matroska.
In this case the chapter ids are offset by 1 to make them nonnegative.
Yet offsetting won't fix duplicate ids, therefore this is changed to
simply create new chapter uids when the input chapter uids don't conform
to the requirements of Matroska (in which case it can be presumed that
they did not originate from Matroska, so that we don't need to bother
to preserve them).

The test program for the FIFO muxer allocates a buffer without padding
and wraps it into a packet via av_packet_from_data(). This is an API
violation. Furthermore, said buffer leaks in case av_packet_from_data()
fails. Fix both of these issues by using av_new_packet() instead.

If one of the two results of a ternary conditional is a pointer to void,
the type of the whole conditional operator is a pointer to void, even
when the other possible result is not a pointer to void. This loophole
in the type system has allowed mxf_read_local_tags to have a pointer of
type pointer to MXFMetadataSet that actually points to an MXFContext.
