bug#55770: 29.0.50; Feature Request: Hook When battery transitions to low or critical

[T.V Raman]

Lookeding at this more closely,
default value of battery-update-interval is 60s which might be okay for
updating modeline; will having other functions here prove to be an
efficiency hit?

For instance, if playing a sound on entering critical state,  one might
well end up implementing some more logic to decide how often to play a sound.
