fetch() now knows nothing about struct image; it simply loads a file and

returns the allocated buffer.

We may be required to page-align modules, so let's make sure we catch

f59ad50504
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.
