I had actually thought of adding it there first, but then took this
approach assuming it would be more receptive upstream :-). Personally,
I'm on the fence. I like the idea of a single knob to control log level
throughout the daemon, making it a bit easier on admins. On the other
hand, individual knobs are more friendly to those pouring through logs.
I can add a knob in libxl.conf if preferred.
