- Add support for splitting async postgres_backend into read and write halfes. Safekeeper needs this for bidirectional streams. To this end, encapsulate reading-writing postgres messages to framed.rs with split support without any additional changes (relying on BufRead for reading and BytesMut out buffer for writing). - Use async postgres_backend throughout safekeeper (and in proxy auth link part). - In both safekeeper COPY streams, do read-write from the same thread/task with select! for easier error handling. - Tidy up finishing CopyBoth streams in safekeeper sending and receiving WAL -- join split parts back catching errors from them before returning. Initially I hoped to do that read-write without split at all, through polling IO: https://github.com/neondatabase/neon/pull/3522 However that turned out to be more complicated than I initially expected due to 1) borrow checking and 2) anon Future types. 1) required Rc<Refcell<...>> which is Send construct just to satisfy the checker; 2) can be workaround with transmute. But this is so messy that I decided to leave split.
