    \note The Debugger process itself and any helper processes like
166 167
    gdbserver are referred to as 'Engine', whereas the debugged process
    is referred to as 'Inferior'.

    Transitions marked by '---' are done in the individual engines.
    Transitions marked by '+-+' are done in the base DebuggerEngine.
    Transitions marked by '*' are done asynchronously.

    The GdbEngine->setupEngine() function is described in more detail below.

    The engines are responsible for local roll-back to the last
    acknowledged state before calling notify*Failed. I.e. before calling
    notifyEngineSetupFailed() any process started during setupEngine()
    so far must be terminated.
