Bill Richardson 0c8c2e453a Add abstract "cond_t" type to detect state transitions. ...

We often need to watch for transitions between one state and another, so
that we can issue warnings or take action ONCE. This abstracts that "have I
already reacted to this" stuff into a single set of functions.

For example, this code reads a GPIO every time through the loop, but it only
generates an event when the GPIO value changes from 0 to 1:

    cond_t c;

    cond_init_false(&c);

    while(1) {
        int val = read_some_gpio();
        cond_set(&c, val);

        if (cond_went_true(&c))
            host_event(SOMETHING_HAPPENED);

        sleep(1);
    }
