Commands were originally ordered by functional group (e.g. keeping the image management commands together), with arrays used to impose a functionally meaningful order within the group. As the number of commands and functional groups has expanded over the years, this has become essentially useless as an organising principle. Switch to sorting commands alphabetically (using the linker table mechanism). Signed-off-by: Michael Brown <mcb30@ipxe.org>
