4.3.5

util: add util::log module to expose FFmpeg's logging facilities.
filter: add method Source::close() to expose av_buffersrc_close. (#23)
codec: add new encoding/decoding APIs send_frame() / send_eof(), receive_packet() to encoder::{Audio, Video} and send_packet() / send_eof(), receive_frame() to decoder::{Audio, Video} based on modern send/receive APIs (instead of avcodec_decode_video2() / avcodec_decode_audio4() / avcodec_encode_video2() /avcodec_encode_audio2() which have been deprecated since FFmpeg 3.1). Users should consider switching to the new APIs. See documentation in libavcodec/avcodec.h for details. (#28)
util: introduce new Error variant Error::Other { errno } for wrapped POSIX error codes (see the AVERROR macro in libavutil/error.h), and reexport common POSIX error codes under util::error. (#24)

crate: FFmpeg version detection is now automatic, obseleting feature flags ffmpeg4, ffmpeg41, ffmpeg42 and ffmpeg43. The flags are kept as noop for now, will be removed in 5.0.
