We do not set up any kind of virtual addressing before invoking an
ELFBoot image. Reject if the image's program headers indicate that
virtual addresses are not equal to physical addresses.
This avoids problems when loading some RHEL5 kernels, which seem to
include ELFBoot headers using virtual addressing. With this change,
these kernels are no longer detected as ELFBoot, and so may be
(correctly) detected as bzImage instead.

Solaris assumes that there is enough space above the Multiboot modules
to use as a decompression and scratch area. This assumption is
invalid when using iPXE, which places the Multiboot modules near the
top of (32-bit) memory.
Fix by copying the modules to an area of memory immediately following
the loaded kernel.

Refactor the {load,exec} image operations as {probe,exec}. This makes
the probe mechanism cleaner, eliminates some forward declarations,
avoids holding magic state in image->priv, eliminates the possibility
of screwing up between the "load" and "exec" stages, and makes the
documentation simpler since the concept of "loading" (as distinct from
"executing") no longer needs to be explained.

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resources has been revoked by the registrant of the domain.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