[PATCH libpciaccess] Support for 32-bit domains

[Keith Busch]

A pci "domain" is a purely software construct, and need not be limited
to the 16-bit ACPI defined segment. The Linux kernel currently supports
32-bit domains, so this patch matches up with those capabilities to make
it usable on systems exporting such domains.
