device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function. This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree. Reviewed by: peter, dfr
