Powered state in BlueZ 5

Hi,

I'm porting the GNOME stack to BlueZ 5 and I'm hitting one issue. It looks like the Powered state is not persistent anymore:

core: Remove persistent storing of the powered state

doc: Mention that the adapter powered property is not persistent

The problem with this is that if the adapter is switched off with rfkill (that's what the toggles to turn bluetooth on and off do), then when it's switched back on it won't be powered. Should those toggle buttons also take care of powering the adapter? What if the user uses a hardware switch to turn it off? Or is there another way this should be done in BlueZ 5? I couldn't find any documentation about this in [1], but [2] suggests this needs to be handled elsewhere, such as in NM.

Thanks,
Emilio
