Clean the hardware cursor handling up. The most notable change is that it no longer buffers the values in viacursor but uses the ones in cursor instead as they are guaranteed to be always valid. Furthermore it uses local instead global variables where possible, moves the cursor variable in shared as only one hardware cursor is supported and returns an error if memory allocation fails. Last but not least it fixes a too small buffer (as u32 has only 4 and not 32 bytes) but this did not produce any known problems. This is mostly a code cleanup, no negative runtime changes are expected.
