Should show power dialog when turning on screen with a long-press

[Michael Terry]

To work around the power dialog appearing on resume, I implemented a band-aid fix [1] that prevented showing the dialog when the screen was off. But I didn't think of the case where you are waking up your device with an intentional long-press to show the power dialog.

Currently, we don't show the dialog, we just turn on the screen. Ideally we'd also show the power dialog.

This is a break-out bug from bug 1445662.

-------------UX comment-------------

When the screen is in idle mode and you long press the power button the following should happen:

1. Screen turns on and stays on
2. Power Dialog popps up after the same delay as if the screen was turned on already.

I checked Android and iOS and all of then ask for confirmation from the user.

Please refer to the Screen blanking policy document for the correct behaviour: https://docs.google.com/document/d/1RBoVknCLZ4GQ8E_iVftd3i_KmdxI5d6JrBt7i5EDZO0/edit?usp=sharing

Wait, I did some market research. I don't know about iOS, but Android does the following:

1) Screen comes on upon button press (not button release like we do)
2) The power dialog still does not show after it comes on and you keep holding the button

I think #1 makes sense to do. And #2 makes me wonder if we want to show the dialog either. Looping in design team.

iOS definitely comes on with a slider to power down, because I've have to use that every now and then when the phone gets hot :)

Status changed to 'Confirmed' because the bug affects multiple users.

Well now I really want designer input, if competitors differ in approach. :)

But still, I think #1 is a no-brainer.
