Rather than add runtime overhead of installing completion handlers, do it statically at build time. This requires a new build time helper macro to declare a command and the completion handler at the same time. Then we convert the env related funcs over to this. This gives an opportunity to also unify the U_BOOT_CMD macros. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
