Add __OwningControllerFD to allow controllers without controlports

This feature should help programs that want to launch and manage a
Tor process, as well as programs that want to launch and manage a
Tor instance in a separate thread.  Right now, they have to open a
controlport, and then connect to it, with attendant authentication
issues.  This feature allows them to just start with an
authenticated connection.

Bug 23900.
