qemu can load an option ROM which is not associated with a particular
PCI device using the "-option-rom" syntax.  Under these circumstances,
we should ignore the PCI bus:dev.fn address that we expect to find in
%ax on entry to the initialisation vector.

Fix by using the PCI bus:dev.fn address only if it is non-zero.  Since
00:00.0 will always be the host bridge, it can never be the address of
a network card.

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resources has been revoked by the registrant of the domain.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.
