  lib: Add o_stream_set_finish_also_parent() and _finish_via_child()

These allow controlling on both directions whether o_stream_finish() should
be finishing the parent stream. If either one is set to FALSE, the parent
stream isn't finished. Which one of these to use depends on the situation.

  Changed paths:
    M src/lib/connection.c

  Log Message:
  -----------
  lib: connection - Use o_stream_set_finish_via_child(FALSE)

This allows o_stream_finish() calls on child streams without closing this
parent stream. Since the stream has no error checking by default anyway,
this allows the connection stream to be used more easily.

  Log Message:
  -----------
  lib-mail: ostream-dot - Set o_stream_set_finish_also_parent(FALSE) by default

ostream-dot is always used inside another ostream to implement some kind of
data escaping. The ostream-dot always has to be finished to write the "."
line, but the caller never wants it to finish the parent stream.

  Log Message:
  -----------
  doveadm-server: Deinitialize log proxying before closing SSL iostream

Otherwise the SSL iostream destroying may trigger debug/error logging,
which attempts to proxy logs when the stream is already closed. This
caused a panic.
