Do not propagate the return value of avformat_write_header(),
as it contains the information whether the output had
already been initialized in avformat_init_output(),
but this is set generically; the return value of
FFOutputFormat.write_header is not documented at all
(and is currently ignored if >= 0), but it is more future-proof
to simply return 0 on success.

This patch populates the third entry for HLS codec attribute using the
AAC profile.
The HLS specifications[1] require this value to be the Object Type ID as
referred to in table 1.3 of ISO/IEC 14496-3:2009[2].
The numerical constants in the code refer to these OTIs minus one, as
documented in commit 372597e[3], confirmed by comparing the values in the
code with the values in the table mentioned above.

Deprecate AVStream.side_data and its helpers in favor of the AVStream's
codecpar.coded_side_data.
This will considerably simplify the propagation of global side data to decoders
and from encoders. Instead of having to do it inside packets, it will be
available during init().
Global and frame specific side data will therefore be distinct.

It is of no value to the user, because every muxer can always
be flushed with a NULL packet. As its documentation shows
("If not set, the muxer will not receive a NULL packet in
the write_packet function") it is actually an internal flag
that has been publically exposed because there was no internal
flags field for output formats for a long time. But now there is
and so use it by replacing the public flag with a private one.

It is only included because two very rarely used functions
use pointers to URLContexts; use struct URLContext instead.
Also move ffio_geturlcontext() so that one can avoid
a forward declaration of struct URLContext (which would be

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are

AVCodec is only ever used as an incomplete type (i.e. via a pointer
to an AVCodec) in avformat.h and it is not really part of the core
of avformat.h or libavformat; almost none of our internal users
make use of it (and none make use of hwcontext.h, which is implicitly
included). So switch to use struct AVCodec, but continue to include
codec.h for external users for compatibility.
Also, do the same for AVFrame and frame.h, which is implicitly included
by codec.h (via lavu/hwcontext.h).
Also, remove an unnecessary inclusion of <time.h>.

This commit does for AVOutputFormat what commit
20f9727018 did for AVCodec:
It adds a new type FFOutputFormat, moves all the internals
of AVOutputFormat to it and adds a now reduced AVOutputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for muxers (it is still a mess due to lavd).

The general demuxing API uses parsers and decoders. Therefore
FFStream contains pointers to AVCodecContexts and
AVCodecParserContext and lavf/internal.h includes lavc/avcodec.h.
Yet actually only a few files files really use these; and it is best
when this number stays small. Therefore this commit uses opaque
structs in lavf/internal.h for these contexts and stops including
avcodec.h.
This also avoids including lavc/codec_desc.h implicitly. All other
headers are implicitly included as now (mostly through codec.h).

This allows for wider compatibility with older devices, such as those
running iOS 3. The only difference between HLS version 2 and version 3 is
that version 3 supports non-integer EXTINF values, and as such, we can
default to version 2 if we're using whole-integer EXTINFs anyways, when
`-hls_flags round_durations` is set.
As this code seems to otherwise consistently use the lowest compatible
version, this seems to fit in properly with existing behavior.
Testing confirms with that this patch, HLS output can work all the way back
to iOS 3.

Otherwise there is no way to detect an error returned by avio_close() because
ff_format_io_close cannot get the return value.
Checking the return value of the close function is important in order to check
if all data was successfully written and the underlying close() operation was
successful.
It can also be useful even for read mode because it can return any pending
AVIOContext error, so the user don't have to manually check AVIOContext->error.
In order to still support if the user overrides io_close, the generic code only
uses io_close2 if io_close is either NULL or the default io_close callback.

It only uses an AVIOContext and an AVBPrint.
When doing so, it turned out that several non-users of
ff_read_line_to_bprint_overwrite() and ff_bprint_to_codecpar_extradata()
relied on libavformat/internal.h to include bprint.h or avstring.h
for them. In order to avoid a repeat of this and in order to reduce
unnecessary dependencies, a forward declaration of struct AVBPrint is
used instead of including bprint.h.
