As mentioned in UPDATING the change below requires the hal port
to be recompiled in order to continue to work. On !386 you
additionally need to update to xorg-server-1.4_1,1.
Regarding common ports affected by the introduction of support
for PCI domains these two ports should be it.
Other consumers of <sys/pciio.h> potentially also need to be
recompiled and adjusted, f.e. sjog needs to be recompiled but
should need no changes. Generally, if a port uses pc_bus it
also needs to deal with pc_domain now.

Log:
Make the PCI code aware of PCI domains (aka PCI segments) so we can
support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the
devices as seen by the OS and represented by PCI location strings.
This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.
