  Log Message:
  -----------
  lib-ssl-iostream: openssl: Make verbose logging robust against i_debug() writing to stream itself.

In dsync, i_debug() is overridden to write to the SSL stream itself through a
multiplexed data stream. So, during the i_debug() call all kinds of things can
happen to the persisted error string in the stream, which caused problems.

  Log Message:
  -----------
  doveadm: dsync: Switch ioloop for input/output streams while making TCP connection.

This task is performed in a sub-ioloop, and when returning from that ioloop, the
output stream would sometimes still have an object on the sub-ioloop that was
just destroyed.
