0. WHIP Version 3.
1. The WHIP muxer has been renamed and refined,
with improved logging context and error messages for SSL, DTLS, and RTC.
2. Magic numbers have been replaced with macros and extracted to functions,
and log levels have been altered for better clarity.
3. DTLS curve list has been updated,
and SRTP profile names have been refined for FFmpeg and OpenSSL.
4. ICE STUN magic number has been refined,
and RTP payload types have been updated based on Chrome's definition.
5. Fixed frame size has been refined to rtc->audio_par->frame_size,
and h264_mp4toannexb is now used to convert MP4/ISOM to annexb.
6. OPUS timestamp issue has been addressed,
and marker setting has been corrected after utilizing BSF.
7. DTLS handshake and ICE handling have been optimized for improved performance,
with a single handshake timeout and server role to prevent ARQ.
8. Consolidated ICE request/response handling and DTLS handshake into a single function,
and fixed OpenSSL build errors to work with Pion.
9. Merge TLS & DTLS implementation, shared BIO callbacks, read, write,
print_ssl_error, openssl_init_ca_key_cert,
init_bio_method function and shared same data structure
10. Modify configure that whip is enabled only dtls is
enabled(just support openssl for now) to fix build error

This commit will properly set the duration field of Opus AVPackets.
Currently, duration is set to 0 on Opus packets from the RTP demuxer.
The Ogg muxer depends on the duration field to properly compute the page granule
value. Without a proper duration, the granule will be wrong, and result in
negative pts values in ogg files.
See oggenc.c:657 (ogg_write_packet_internal)
This commit calculates using the opus_duration function, which was copied
from oggparseopus.c
I moved this functionality and the existing opus extradata functionality
(added by me in 6c24f2b) into a new rtpdec_opus.c file.

Add RTP packetizer and depacketizer according to (most)
of the official AV1 RTP specification. This enables
streaming via RTSP between ffmpeg and ffmpeg and has
also been tested to work with AV1 RTSP streams via
GStreamer.
It also adds the required SDP attributes for AV1.
AV1 RTP encoding is marked as experimental due to
draft specification status, debug amount reduced
and other changes suggested by Tristan.
Added optional code for searching the sequence
header to determine the first packet for broken
AV1 encoders / parsers.
Stops depacketizing on corruption until next keyframe,
no longer prematurely issues packet on decoding if
temporal unit was not complete yet.

There is no benefit in using it: The fast path of copying
is not taken because of misalignment; furthermore we are
only dealing with a few byte here anyway, so simply copy
the bytes manually, avoiding the dependency on bitstream.c
in lavf (which also contains a function that is completely
unused in lavf).

Use SHLIBOBJS and STLIBOBJS in the Makefiles for avcodec and avformat,
and add a stub ffjni.c to libavformat, which allows the symbols to be
duplicated for shared builds but not static builds.

RCWT (Raw Captions With Time) is a format native to ccextractor,
a commonly used OSS tool for processing 608/708 Closed Captions (CC).
RCWT can be used to archive the original extracted CC bitstream.
The muxer was added in January 2024. In this commit, add the demuxer.
One can now demux RCWT files for rendering in ccaption_dec or interop
with ccextractor (which produces RCWT). Using the muxer/demuxer combo,
the CC bits can be kept for processing or rendering with either tool.
This can be an effective way to backup an original CC stream, including
format extensions like EIA-708 and overall original presentation.

This muxer solely exists to test the fifo muxer via a dedicated
test tool in libavformat/tests/fifo_muxer.c. It fulfills no
other role and it is only designed with this role in mind.
The latter can be seen in two facts: The muxer uses printf
for logging and it simply presumes the packets' data to contain
a FailingMuxerPacketData (a struct duplicated in fifo_test.c
and tests/fifo_muxer.c.); in particular, it presumes packets
to have data at all, but this need not be true with side-data
only packets and a segfault can easily be triggered by e.g.
encoding flac (our native encoder sends a side-data only packet
with updated extradata at the end of encoding).
This patch fixes this by moving the test muxer into the fifo
test tool, making it inaccessible via the API (and actually
removing it from libavformat.so and libavformat.a).
While this muxer was accessible via e.g. av_guess_format(),
it was not really usable for an API user as FailingMuxerPacketData
was not public. Therefore this is not considered a breaking change.
In order to continue to use the test muxer in the test tool,
the ordinary fifo muxer had to be overridden: fifo_muxer.c
includes lavf/fifo.c but with FIFO_TEST defined which makes
it support the fifo_test muxer. This is possible because
test tools are always linked statically to their respective
library.

Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly
used open source tool for processing 608/708 closed caption (CC) sources.
It can be used to archive the original, raw CC bitstream and to produce
a source file file for later CC processing or conversion. As a result,
it also allows for interopability with ccextractor for processing CC data
extracted via ffmpeg. The format is simple to parse and can be used
to retain all lines and variants of CC.
A free specification of RCWT can be found here:
https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT
This muxer implements the specification as of 01/05/2024, which has
been stable and unchanged for 10 years as of this writing.
This muxer will have some nuances from the way that ccextractor muxes RCWT.
No compatibility issues when processing the output with ccextractor
have been observed as a result of this so far, but mileage may vary
and outputs will not be a bit-exact match.
Specifically, the differences are:
(1) This muxer will identify as "FF" as the writing program identifier, so
as to be honest about the output's origin.
(2) ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning
data differently than ccextractor from embedded SEI/user data.
For example, DVD captioning bytes will be translated to ATSC A53 format.
This allows ffmpeg to handle 608/708 in a consistant way downstream.
This is a lossless conversion and the meaningful data is retained.
(3) This muxer will not alter the extracted data except to remove invalid
packets in between valid CC blocks. On the other hand, ccextractor
will by default remove mid-stream padding, and add padding at the end
of the stream (in order to convey the end time of the source video).
This prevents code duplication in the source form by calling the parse
code that was moved to avcodec last commit. The code will be duplicated
in binary form for shared builds (it's not that large), but for source
code it will only exist in one location now.
