    daemon: Introduce DisplayBrightnessDetector interface · eb89fe2a
    Jakob Petsovits authored
    After detection, the rather minimal interface provides a list of
    displays supporting brightness operations, incl. change signal.
    ScreenBrightnessController gets adapted to make use of it.
    
    BacklightDetector is split out from BacklightBrightness to support
    this new interface. The existing DDCutilBrightness gets renamed to
    DDCutilDetector to keep some semblance of naming consistency.
    
    In theory, this would switch your brightness controls between
    internal laptop display and DDC-supporting monitors when one of
    them disappears. In practice, behavior is still unchanged because
    laptop displays are first in priority order and never disappear
    if they're present at all.
