The "vram" setting returns the (Base64-encoded) contents of video RAM,
and can be used to capture a screenshot.  For example: after running
memtest.0 and encountering an error, the output can be captured and
sent to a remote server for later diagnosis:

  #!ipxe
  chain -a http://server/memtest.0 && goto ok || goto bad
  :bad
  params
  param errno ${errno}
  param vram ${vram}
  chain -a http://server/report.php##params
  :ok

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resources has been revoked by the registrant of the domain.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

EFI provides a copy of the SMBIOS table accessible via the EFI system
table, which we should use instead of manually scanning through the
F000:0000 segment.
