Extend libpci API with a new option PCI_FILL_PARENT to fill parent device for the current enumerated device. This can be useful in situation when non-complaint PCI-to-PCI bridge-like device with Type 0 header is present in the system and behind this bridge are either endpoint devices or another non-compliant bridges. This applies e.g. for notoriously broken Galileo and Marvell PCI and PCIe devices. lspci can will use PCI_FILL_PARENT information from the system if config space does not provide enough information to build topology.
