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resources has been revoked by the registrant of the domain.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

The vxge driver code is split over several files, including vxge_main.c.
This causes the build system and ROM-o-matic to see the driver as
"vxge_main".

This patch adds a stub vxge.c which takes up no space but gives the
driver its proper name, "vxge".
