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);
}

This is needed for non-volatile register emulation. Also, this can be
used to implement system jump or reset flags.

This is the first version of pthread-based RTOS emulator. With this, we
will be able to test high-level modules entirely on the host machine.
