We may be required to page-align modules, so let's make sure we catch
it if we don't.

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.

Distinguish between ENOMEM (as representing a lack of internal memory
as allocated by malloc()) versus all other errors, in particular
ENOBUFS (representing a lack of external buffer space, e.g. in a
device's TX queue or a user buffer).
