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
