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

Improves compatibility with Resolume products by adding an additional
hashtable for DXT color+LUT combinations, and padding the DXT texture
dimensions to the next largest multiple of 16. Produces identical
packets to Resolume Alley in manual tests.

Since a51279bbde,
hpeldsp_rnd_template.c was only included once and
one of the two functions in rnd_template.c was
only enabled once.

The code to initialize the ungrouped bap mantissa tables
(bap 3 or 5) takes more bytes of .text than the tables itself;
they have therefore been hardcoded.
For GCC (14, -O3, albeit in an av_cold function), the initialization
code takes 99B each for the fixed and floating point decoders
(the code is currently duplicated), whereas the hardcoded tables
only take 96B. For Clang 19 it were 374B each (I don't now what
Clang was doing there).

Setting print_graphs_format (in case no -print_graphs_format
option was specified) is racy, as is using av_strtok()
to split it. Both have been removed.
Notice that using av_strtok() was destructive: In the absence
of races the options would only have been applied for the
first initialization.

As the names imply, they are structs meant to be internal and private to the
filter handling code. If a field is required in other modules, then it can
be moved to the public facing structs, which is done in this commit.

The follow cmd output corrupted file before the patch:
ffmpeg -f lavfi -i color=blue,trim=duration=0.04 \
-f lavfi -i anullsrc,atrim=duration=2 \
-movflags +empty_moov+hybrid_fragmented \
-frag_duration 1000000 \
-frag_interleave 1 \
output.mp4
1. first_track is the first track with track->entry != 0. As in the
command above, video track (track index 0) has a single frame. When
flush the second fragment, first_track is 1, the audio track.
2. write_moof = i == first_track, so write_moof is false for i = 0.
3. When mov->frag_interleave != 0, mov->mdat_buf != NULL, because
it contains audio data. So avio_write is called before write_moof,
that is, the data write before moof, and mov_finish_fragment
executed with wrong mdat_start.
4. With normal fmp4 output, the error isn't obvious. With
hybrid_fragmented, ffplay output.mp4 shows a lot of error messages.

The default behavior for VVenC (since v1.10.0) is to create an IDR with
leading pictures for the first picture in decoding order (POC 32). This
leads to FFmpeg generating an edit list with an empty entry, skipping
the leading pictures.
This patch fixes the calculation for the start_pts, while the DTS is
negative (as produced by vvenc).
