[embed] Add missing register_image() to image/embedded.c
...
When the embedded image is a script, the unregister_image() performed by
image/script.c corrupts memory, since image/embedded.c omitted the call
to register_image().
This is the first bug fixed using Stefan Hajnoczi's gdb stub for gPXE.

Set current working URI to be that of the executable image when

executing any image, not just a script. (This will enable pxelinux to
use relative URIs, should it wish to.)

Scripts temporarily deregister themselves while executing. This

allows us to avoid execution loops without having to hack around the
image registration order.

Actually, the initrd image should be architecture-independent.

Provide registration mechanism for loaded images, so that we can e.g.
...
refer to them by name from the command line, or build them into a
multiboot module list.
Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.

Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF
