replaces it with equivalent information found in the driver_data field
of the pci_device_id structure.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain.  Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.

Also update README, LOG and COPYRIGHTS to remove obsolete information.

Add FILE_LICENCE declarations to almost all files that make up the
various standard builds of gPXE.

This is a completely rewritten version of the rtl8169 family driver
using the gPXE driver API.
