d97a073d1b
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.

e7f4babf41
Starts taking steps towards SMS/GG and V9938/9958 support.
...
Specifically: routine namespace stuff, plus the intention to move to a table-based operation+cost version of timing. Reordering works fine for the TMS, and probably would also for the SMS/GG, but it'd be problematic with the command engine of the V9938/9958 and maintaining a consistent set of code is easier.
