We can get the low voltage interrupt trigger sometimes way too early, maybe because of CPU load spikes. This causes orderly_poweroff() be called too easily.

Let's check the voltage before orderly_poweroff in case it was not yet a permanent condition. We will be getting more interrupts anyways if the condition persists.

Let's also show the measured voltages for low battery and battery empty warnings since we have them.

This is a tweak of power management parameters, not a fix for serious bug.

Plus, it needs a lot of testing it did not get, yet.

Please drop from stable. Pavel
