Moves drawing into the next timer tick after retrace if sync locked.
...
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.
This should completely eliminate tearing for machines that can be synced to the native output rate.

Gets to slightly adjusting execution speed and matching up respective vertical syncs.

I probably still need to move the ->draw inline.

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.

Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation.
...
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.

With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.
