bitbake/lib/bb/event.py:

    Introduce a NoProvider Event. It contains
    a 'runtime' flag, the item name and the
    configuration data.

bitbake/bin/bitbake:
    Fire the NoProvider event at some spots. There
    are more events we need to fire. Ideally the
    BitBake UI would just be a handler...
