  - Implement FunctionalityReadyNotifierImpl

    BundlesBootedReady was already removed
    earlier in Ice9cd60878a68037dfcdb384979aabe426cf0a6b.

    The BundlesBootedReady was one of my dumber ideas... ;-) because, as
    Faseela pointed out in our discussion of diagstatus today, if someone
    made some other service dependent on the BundlesBootedReady, e.g. with
    an @Inject @OsgiService (or a <service> in BP XML), then that would
    create a sort of soft cyclic dependency (not a hard one, SFT would
    probably not fail on BP?), because the SystemReadyMonitor would never
    reach system state ready ACTIVE - because it would wait on the service
    with the dependency to BundlesBootedReady, which means waiting for
    SystemReadyMonitor ready, which ... you get the idea.

    The *ONLY* valid way to get notified of ready-ness is through the
    SystemReadyMonitor registerListener onSystemBootReady().

    The FunctionalityReady idea itself still has value though, for any
    "higher level" ready-ness signaling; e.g. Daexim's boot-on-import
    completed (and I'll put in a change which makes that use this next); but
    that is different because it does NOT block
