pciconf: Add a tree modeHEADmain

This lists PCI devices in a hierarchy showing the parent/child
relationship of PCI devices and bridges.  While this is inspired by
lspci -t output, the format is closer to ps -d and also prefers using
new-bus device names when possible.  If a device does not have a
driver, the PCI selector is output in place of the device name.

When the -v flag is given, the vendor and device ID strings are output
after the device name.  If a string for an ID isn't found, the hex ID
values are output instead.
