Start reading incoming messages and pass them to on_message, until it returns Stop _.

on_end_of_batch is called after processing a batch of messages, before waiting for the file descriptor to become readable again.

val read_one_message_bin_prot :

  'a Core.Bin_prot.Type_class.reader ->
  ('a, [ `Closed | `Eof ]) Core.Result.t Async_kernel.Deferred.t

Convenience function to wait for the first message and un-bin_prot it.

Async RPC uses this to handle the handshake at the beginning of the message stream.
