Summary: The comment in the Editine.h header made it sound like editline was just unable to handle terminal resizing. We were not ever telling editline that the terminal had changed size, which might explain why it wasn't working. This patch threads a `TerminalSizeChanged()` callback through the IOHandler and invokes it from the SIGWINCH handler in the driver. Our `Editline` class already had a `TerminalSizeChanged()` method which was invoked only when editline was configured. This patch also changes `Editline` to not apply the changes right away in `TerminalSizeChanged()`, but instead defer that to the next character read. During my testing, it happened once that the signal was received while our `ConnectionFileDescriptor::Read` was allocating memory. As `el_resize` seems to allocate memory too, this crashed.
