Only attempt to list extended capabilities for devices that have a

the code relied on these reads returning 0xFFFFFFFF.

allowed to use it (unlike manual config register access which requires

Make selector parsing accept the dot "." as an alternative selector
with identical meaning as the colon ":". This is to support a syntax
that is more similar to a PCI device specification in the device hints
file. The selector is not fully compatible with the specification in
the hints file, since entries in that file use a different prefix,
which needs to be added to the getsel() routine, if full support of
that syntax is found to be desirable.

Restore compatibility with version before introduction of PCI domains.
PCI selectors with 2 or 3 elements behave exactly as before (i.e. the
domain is 0 and in the 2 element case, the function is also 0).
The form with 4 selector elements works as in the previous revision
and provides the PCI domain number as the left-most selector element.

This change allows old scripts (which used the 2 or 3 selector element
formats) to be kept. Without this patch, the 3 element form was parsed
as starting with a domain number (and the function was assumed to be 0),
with this patch, the domain is assumed to be 0 (and the last value is
used as the function number).

The man page is updated to describe the new selector semantics.

Approved by: re (Ken Smith)

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.

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.
