This change makes it possible for child encoders to define custom profile
option names which can be used for setting the AVCodecContext->profile.

Also rename unit name to something rather unique, so it won't be used elsewhere.

This will be used for AVCodecContext->profile. By specifying constants in the
encoders we won't have to use the common AVCodecContext options table and
different encoders can use the same profile name even with different values.

Move the copying of the frame to vos_data further up in the function,
so that when writing the actual frame data for the first frame, it's
clear that the stream really is in annex b format, for the cases where
we create extradata from the first frame.

Alternatively - we could invert the checks for bitstream format. If
extradata is missing, we can't pretend that the bitstream is in
mp4 form, because we can't even know the NAL unit length prefix size
in that case.

Also avoid creating extradata for AVC intra. If the track tag is
an AVC intra tag, don't copy the frame into vos_data - this matches
other existing cases of how vos_data and TAG_IS_AVCI interact in
other places.

EAGAIN is returned when input is provided but can't be consumed. The filtering
process is unaffected in this case, and the function will be able to consume
new input after retrieving filtered packets with av_bsf_receive_packet().

Remove the line about empty packets never failing added in
41b05b84 while at it. Even if it's currently
the case, it unnecessarily constrains the API and could be changed in the future
in case it needs to be extended.
The user should always check for errors and never expect a call to never fail.

This will allow adding a public header named bsf.h

Use 0, which selects the alignment automatically.

It is not a public header and has not been used since
10173c0e

And enable it in all modes by default.

av_stream_get_side_data() tells the caller whether a stream has side
data of a specific type; if present it can also tell the caller the size
of the side data via an optional argument. The Matroska muxer always
used this optional argument, although it doesn't really need the size,
as the relevant side-data are not buffers, but structures. So change
this.

Furthermore, relying on the size also made the code susceptible to
a quirk of av_stream_get_side_data(): It only sets the size argument if
it found side data of the desired type. mkv_write_video_color() checks
for side-data twice with the same variable for the size without resetting
the size in between; if the second type of side-data isn't present, the
size will still be what it was after the first call. This was not
dangerous in practice, as the check for the existence of the second
side-data compared the size with the expected size, so it would only be
problematic if lots of elements were to be added to AVContentLightMetadata.

Some real-world sites use an authorization header with a bearer token; when
combined with lengthy request parameters to identify the video segment,
it's rather trivial these days to have a request body of more than 4k bytes.

MAX_URL_SIZE is hard-coded to 4k bytes in libavformat/internal.h, and
HTTP_HEADERS_SIZE is 4k as well in libavformat/http.h, so this patch increases
the buffer size to 8k, as that is the default request body limit in Apache, and
most other httpds seem to support at least as much, if not more.
