The code now has a single, consistant flow for all three ioctl variants. ifdefs and for pre-FreeBSD-7 compatability are moved to functions and macros. So the flow is alwasy the same, we impose the cost of allocating, copying to, updating from, and freeing a copy of struct pci_conf_io on all paths. This change will allow PCIOCGETCONF32 support currently in sys/compat/freebsd32/freebsd32_ioctl.c to be moved here.
