Adds optional stereo output for the AY.
...
The real chip provides the three tone channels as separate outputs, so a variety of different mixings can exist.

All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine.

Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

Adds the necessary routine for all machines to be able to respond to get_scan_status.

They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
