Serial output depends on polling in sections where interrupts are disabled

Ok, learned something today ;-)

The PR has now been merged to development btw.

@Yveaux While we are at this topic .. any chance to let the user-code know what caused the wakeup during sleep() ??

For example .. if there was a wakeup at all or which of the two interrupt sources was the cause.

Unforunatly the "cause" gets cleaned up at the end of hwSleep:

bool interruptWakeUp()
{
    return _wokeUpByInterrupt != INVALID_INTERRUPT_NUM;
}

Calling this from user-code will always return 0 as the end of hwSleep does this:

 _wokeUpByInterrupt = INVALID_INTERRUPT_NUM;

Not clearing the "last interrupt source" would be nice.

@cimba007 The return value of sleep() indicates the wake-up cause: irq (nr) or timer (=MY_WAKE_UP_BY_TIMER).
See here: https://github.com/mysensors/MySensors/blob/development/core/MyHwATMega328.cpp#L146-L147

I also confirm it fixed my problem. Thank you!

@tekka Thanks, that is what I was looking for

@Yveaux Thank you for committing this fix. I had the same issue and it caused me a lot of headache
