So this is similar but not identical to what music-app did.

There's a qtpowerd source package in the coreapps-drivers daily PPA that will wrap Powerd's requestSysState API; for mediaplayer-app we need some similar wrapper for requestDisplayState API.

So we need to add this feature to qtpowerd, move qtpowerd from PPA to archive, use the feature in mediaplayer-app.

There's currently some music-app hardcoding in qtpowerd too.
