Contrary to the existing Task Sink, the Async and Sync Mutex Sinks handle buffers in the `PadSinkHandler` directly. The Async Mutex Sink uses an async Mutex for the `PadSinkHandlerInner` while the Sync Mutex Sink uses... a sync Mutex. All Sinks share the same settings and stats manager. Use the `--sink` command line option to select the sink (default is `sync-mutex` since it allows evaluating the framework with as little overhead as possible. Also apply various fixes: - Only keep the segment start instead of the full `Segment`. This helps with cache locality (`Segment` is a plain struct with many fields) and avoids downcasting the generic `Segment` upon each buffer handling. - Box the `Stat`s. This should improve cache locality a bit. - Fix EOS handling which took ages for no benefits in this particular use case. - Use a macro to raise log level in the main element. - Move error handling during item processing in `handle_loop_error`. This function was precisely designed for this and it should reduce the `handle_item`'s Future size.
