[Ovmsdev] "Vehicle is idling": A new "Feature"?

[Michael Balzer]

Greg, Mark,

that's actually a very old feature originating from V2. It's meant to alert about a car left turned on, which is both a potential security issue
(key is plugged) and a potential fire/explosion threat on vehicles that may overcharge the 12V battery from the DC/DC converter. It's also main
battery drainage.

This also needs to trigger during charging, but of course not if the vehicle wakes itself for some internal checks or OTA updates / whatever.

This was/is using the definition of "awake" as "turned on", and "on" as "ignited". It seems all cars except the roadster follow this scheme now,
so maybe we should separate the "maintenance awake" state?

Regards,
Michael
