Create separate private key for midispcur cursor bits

The CursorScreenKey array is supposed to be used by the DDX for cursor
private data, but midispcur was abusing it to hold cursor bits private
information. Create a separate set of privates for the dispcur cursor
bits information.

This also renames the device private index and macros to better
reflect their usage:

	miDCSpriteKey -> miDCDeviceKey
	MIDCBUFFER -> miGetDCDevice
