In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

Attempts better to hide C1540 implementation details from the reader.

In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Reformulates the Oric more cleanly into the modern world.
...
Specifically: now that the implementation is contained within the CPP file, there's no need to embed the keyboard, tape player and VIA port handler as private classes. Also the pain of additional syntax is reduced, so the keyboard has been bumped up to a fully data-hiding class. I've also transferred overall ownership of the tape player, AY and keyboard up to the Oric itself, with the VIA merely being wired to them, and added a whole bunch of extra documentation.

Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.

Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over.

Breaks apart the CPC's 6845 bus handler to obey phase 1 and phase 2, and now back-dates interrupts when appropriate.

Permits the 6845's bus state to be examined by an owner, eliminating the need to buffer it in the bus handler. But more than that it allows the CRTC to decide when it adjusts the various outputs respective to the main phase. So a net effect of the change is that the CPC now sees vsync a cycle earlier, because my current reading of the 6845 datasheet is that it is set at the end of phase 1, not the beginning of the next phase 1.

Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.

Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this will often be that of the superclass and not that of the derived class known to the CPC.

Worked logic all the way down to the CPC. If the 8272 announces that it is asleep, it is now no longer clocked. Also very slightly cut down on IRQ line chatter to the Z80.

Step one towards cutting much of this cost: build only the table that's appropriate for the current mode, and at least declare when a more minimal change would be sufficient.
