Comment (by nickm):

 If this is just about log messages, it's easier to do.

 If it's about _everything_ sent over stdout or stderr, that is less easy.

 A callback is not what I'd favor here, since libtorrunner.a couldn't
 support it easily, and since introducing a system of callbacks would
 complicated the control flow between tor and its embedding applications.
 But maybe we can make capturing this stuff easier.  The early-log-messages
 ideas in #10059 might help here, as might some mechanism to have the
 owningcontrollerfd feature start out with a preconfigured set of events.
