Introduce the possibility of operation type as a template parameter.
...
It's already proven possible to provide this for instruction fetch, so I think it'll immediately be a win. But more importantly it opens a path forwards for further improvement.

Starts to introduce a new grammar for ROM requests.

Makes absolutely sure not to try to use quickboot workaround for Mac 128kb/512kb.
...
Albeit that it should be harmless; it's just seeding RAM.

Splits 'CRTMachine' into three parts: ScanProducer, AudioProducer, TimedMachine.

Simultaneously cleans up some of the naming conventions and tries to make things a bit more template-compatible.

Starts a switch to reflectable-style runtime options.
...
The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.

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.

Logic being: name these things for the bus action they model, not the effect they have.

Removes clock for NCR 5380.
