Modify pciconf(8) so that it will print out PCI devices that have no driver
configured in the kernel. It gives them a device name of "none" and monotonically incrementing unit numbers. (starting at 0) Before, pciconf would just skip over unconfigured devices. (unconfigured devices can be detected because they have a null string for a device name) Update the man page to reflect the new pciconf output. Unfortunately, this causes the sample 'pciconf -l' output lines to wrap, but I'm not sure what to do about that really. If anyone presents a reasonable case for printing out something other than "none1" for unconfigured devices, I'm willing to listen.
