This compared to the other suggestions is cleaner and easier to understand
keeping the condition in the if() simple.
This affects alot of fate tests.

This introduces two new AVOption options for the FTP protocol,
one named ftp-user to supply the username to be used for auth,
one named ftp-password to supply the password to be used for auth.
These are useful for when an API user does not wish to deal with
URL manipulation and percent encoding.
Setting them while also having credentials in the URL will use the
credentials from the URL. The rationale for this is that credentials
embedded in the URL are probably more specific to what the user is
trying to do than anything set by some API user.

A too big picture will case the muxer to write a truncated block size (uint24)
causing the output file to be corrupt.
How to reproduce:
Write a file with truncated block size:
ffmpeg -y -f lavfi -i sine -f lavfi -i color=red:size=2400x2400 -map 0:a:0 -map 1:v:0 -c:v:0 bmp -disposition:1 attached_pic -t 1 test.flac
Try to decode:
ffmpeg -i test.flac test.wav

There have been many reports over the years about problems when
taking an HLS stream as input to `ffmpeg` where there are timestamp
discontinuities present. This is explicitly supported in the
HLS spec (EXT-X-DISCONTINUITY) and often used for ad injection.
Various fixes and work-arounds have been proposed over the years,
but one step that seems obvious, even if it's not a complete fix,
is to mark the HLS input format as supporting discontinuities. This
will prevent timestamp fixup logic in ffmpeg.c kicking in that ends
up mangling the timestamps unnecessarily.
I've tested this out with an example provided by Joe Koberg early
last year, and it is sufficient to allow `ffmpeg` to download and
mux the stream correctly. Joe had briefly suggested that other
situations can still be handled incorrectly, but this seems like
a strict improvement.
Joe's example:

bswap.h was included since 7b114c09, yet since 3788a3c0 no explicit use
of anything from bswap.h has been made, so remove this header.
(Only AV_RL32 is used and while this might imply swapping on
big-endian systems, it is contained in libavutil/intreadwrite.h.)

Fix #7620
In the case tee muxer with both "bsf" and "use_fifo" parameters
will trigger this bug. Tee muxer will first steal parameters (like "f",
"select"...) and then "use_fifo" will try reading out remaining options
and pass them to fifo as option "format_options".
Current code miss the part of stealing "bsf" options.

In order to fix a potential memleak upon failure, 0b8956b2 made sure that
a buffer given by a pointer was freed upon error. But this pointer was
only initialized upon use and in several cases (Clang gives no fewer
than 13 -Wsometimes-uninitialized warnings) this meant that an
uninitialized pointer was used to free a buffer. So initialize the
pointer.

mkv_start_new_cluster() actually didn't start a new cluster, but ended
the old one instead and emitted a debug message that it had started a
new cluster. This has been changed: The debug message has been moved to
the place that really starts a new cluster and the function has been
renamed to mkv_end_cluster().
Furthermore, without this debug message the function can be used for
flushing.

The Matroska muxer groups index entries with the same pts together in
order to save a few bytes. Because of Matroska's variable-length length
fields, mkv_write_cues() does this by first finding out how many index
entries will be grouped together before actually writing them.
Currently, it is asserted at both of these stages that the stream index
of the list of designated index entries is valid. But the second assert
is redundant, because the very same index entries have already been
checked.

The Matroska muxer up until now leaked memory in two scenarios:
1. If an error happened during writing the trailer, as
mkv_write_trailer() returned early without cleaning up.
2. If mkv_write_header() indicated success despite an error in the
underlying AVIOContext. In this case avformat_write_header() returned
the IO error and according to the API the caller is not allowed to call
av_write_trailer(), so that no cleanup happened for the allocations made
in mkv_write_header().
This has been fixed by using a dedicated deinit function.
