Update the Sun mouse implementation to use QemuInputHandler instead of the legacy qemu_add_mouse_event_handler() function. Note that this conversion adds extra sunmouse_* members to ESCCChannelState but they are not added to the migration stream (similar to the Sun keyboard members). If this were desired in future, the Sun devices should be split into separate devices and added to the migration stream there instead.
