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.
