Arseny Sher 0d8ced8534 Remove sync postgres_backend, tidy up its split usage.
- 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.
