Subject: Encapsulate the old PCI compatability support and APIs completely
 under "options COMPAT_OLDPCI".  This option already existed, but now also
 tidies up the declarations in #include <pci/pci*.h>.  It is amazing how much
 stuff was using the old pre-FreeBSD 3.x names and going silently undetected.
