build/boot/roms: use the new coding style
lbmk's new style is inspired by the bsd coding styles: top-down logic, main simplified to a skeleton showing overall program structure, variables well-defined, rigorous (yet deceptively simple) error checking. this was attempted before, but caused problems; coreboot wasn't being cleaned properly, and rather than audit it, i simply reverted this back to the old style. this is actually attempt number 5, because i made 3 more attempts between then and this one. i've build-tested this using "./build boot roms all" (which is what b0rked on the first attempt, months ago). it should be stable(tm). the code is much nicer to read / work on now. this is the beating heart of lbmk. get this script wrong, and you break all of libreboot.
