Allocate per-screen device/cursor-bits private keys in midispcur
midispcur was abusing the CursorScreenKey to index the cursor_bits privates, it also had a MAXSCREENS array of keys to index device privates. Switch both of these to the new dixCreatePrivateKey API and store a pointer to that in the screen private.
