RTVAX1000: Make sure that rtvax1000 doesn't contain any parts of the VCB01 board which was never supported.

QVSS: Changed prior VSYNC fix to only interrupt quickly immediately after interrupts are enabled to avoid idling issues with the prior fix. From Matt Burke
...
Also fixed Qbus memory reference issues to properly generate a machine check if the QVSS device is disabled and the frame buffer is referenced.

QVSS: Fix to get the VSYNC interrupts to be more reasonable. Addresses Issue #88 . From Mike Burke
...
The vertical sync interrupt generated in vc_svc() was too slow for Ultrix. The driver enables interrupts and then calls DELAY(20000), which I guess is 20ms. This translates to about 10000 simulated instructions, but tmxr_poll works out at ~75000 instructions. I've added a new unit to simulate just the vsync interrupts activating every 8000 instructions.
This approach will completely disable the ability to idle while the QVSS device is enabled.

QVSS: Fix to handle when cursor is near the right edge of the screen and only partially visible.
...
Prior fix for cursor tracking allowed this to now be observed.
The description of the prior change should have been:
The status bits need to be set in the upper byte of the DUART receiver buffer. This is not mentioned in the DEC manual but I found a Phillips datasheet for the 2681 chip, which has a small footnote about it.
