Log:
[NTVDM]
- Finally get rid of console output handles in the BIOS.
- Move console text buffer copy from BIOS back into VGA memory (~= revert part of r61542),
but do it ONLY when attaching the VGA emulation to the console.
- Fix cursor positioning in BIOS & VGA (work in progress).
- Initialize PS/2 after having setting basic console modes.
- Showing/hiding mouse cursor (see the option in the console menu) is done in while()
loops to be sure the cursor is really shown/hidden (based on the return value of
ShowConsoleCursor).
