This seems not to do anything any more since a long time, and removing
it avoids using uninitialized memory. Also change the error value
forwarding as done everywhere else.

Calculation of x an y based on width and height did not work when
width == 0 or height == 0.  "0" substitutes the input width and
height, but did so too late for x, y expression evaluation.

I've got some m4a samples that had jpeg cover art marked as png. Since
these files were supposedly written by iTunes, and other software can
read it (e.g. clementine does), this should be worked around.

Since png has a very simple to detect header, while it's apparently a
real pain to detect jpeg in the general case, try to detect png and
assume jpeg otherwise. Not bothering with bmp, as I have no test case.

Some codecs use the codec_tag to signal specific information and

At least on AIX it conflicts with the close() libc function from unistd.h.

In order to load libraries in Android they need to be unversioned.
The android target section was derived from the BSD ones, and they
that simply drop the SONAME

Drop the need of setting -debug bugs since it's not a bug, and the
message is already under a AV_LOG_DEBUG log level. Instead only print
it when there is an actual string in it.

Some systems may be lacking getservbyport; the previous ifdef wasn't
quite enough since it still assumed that struct servent was defined,
as pointed out by Clément Gregoire.

Simply remove the possibility to return non-numeric services in
getnameinfo; no caller of getnameinfo within libavformat
currently try to use getnameinfo for retrieving the port number without
NI_NUMERICSERV, and falling back on getservbyport may be non-threadsafe.

Pave the way for having the size of the AVPacket struct not part
of the ABI.

As documented, `av_dup_packet` is broken by design, `av_packet_ref`
matches the AVFrame ref-counted API and can be safely used instead.

Make it return an error and check its return value when it is used.
Simplify the usage by calling `av_packet_ref` internally when needed.

`av_packet_unref` matches the AVFrame ref-counted API and can be used as
a drop in replacement.

Deprecate `av_free_packet`.

And drop the av_dup_packet from the input_thread.

Make sure it does not leak packets.
