Disabled a bunch of the caveman debug logging.

Okay, so it seems that sync also works the other way around.

After all that, it seems likely that inputs just aren't inverted for the Vic.

Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.

The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive.

Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps.

Since the ROM is well disassembled, let's actually try to be a 1541 first.

Quick fixes properly to declare the DriveVIA, to ensure its interrupts take effect, and to wire ATN IN to CA1 rather than CB2.

Made an attempt to allow the 1540 to talk back to the Vic, and to receive interrupts. Also slightly disambiguated debugging logging.

Further fleshing out: added a serial port for the serial bus.

Ensured the 1540 ROM gets installed, at least.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.

Created a namespace for Commodore and an empty container file for the 1540[/1] implementation.
