i actually went through all of lbmk and found no
instances where err calls were missing except in
build/boot/roms_helper

where it is set to "both" (grub_scan_disk), inserting
scan.cfg is superfluous, because grub.cfg defaults to
both anyway, unless otherwise specified by scan.cfg,
and only if that file exists within cbfs.
thus, save a bit of build time (only a slight saving)

target.cfg can now specify e.g.
grub_timeout=20
this would then be inserted as timeout.cfg in cbfs,
containing the instruction:
set timeout=20
HP laptops need a bit of extra time, due to the delay
caused by the EC bug workaround deployed in GRUB
desktops in general need extra time. this too is set to
10s, like the HP laptops.
only insert timeout.cfg if actually needed (declared in
target.cfg), otherwise grub.cfg will default to 5s

now under coreboot mainboards, target.cfg can specify
a background. if not specified, the 1280x800 one is
assumed, and used by default. it can be overridden.
the path should be relative to:
config/grub/background/

also: only return zero status if rom images were succesfully
built, and print a list of each rom image directory based on
what was actually compiled, rather than just saying that the
rom images are stored under bin/

libreboot's build system, lbmk, *is* available to use
in releases aswell (use the _src tarball), but it is
mostly intended for development, in lbmk.git
well, there's not much point wasting time / disk space
generating no-microcode roms within lbmk
they should be generated only at release time, alongside
the default ones
this patch implements that, thus speeding up the build
process and saving disk usage during development
the other alternative was to add a new option in
build/boot/roms, -m, that would opt in to removing them,
but this is extra complexity for something that is ill
advised and only provided to appease certain people

most of these steps do not need to be repeated, per image.
move it into handle/make/config, so that the steps are
performed on files that go under elf/coreboot (this will
save on build time).
the logic for handling 4MB ROM images on sandy/ivy was unused,
and has been removed.

new behaviour:
* grub.cfg and grubtest.cfg no longer inserted to cbfs
* grub.cfg in memdisk instead
* grub.cfg in memdisk defers to cbfs/grub.cfg if added
(not added by default, anymore)
* does not defer to grubtest.cfg even if available
* only shows link to grubtest.cfg if available,
as a menuentry item
keymaps:
if /keymap.gkb exists in cbfs, it uses that by default,
but by default this isn't added. instead, it looks for
a file named keymap.cfg and sources that, which then
sets the keymap to one that is located under memdisk.
this file is inserted for each rom, per layout.
if keymap.gkb and keymap.cfg both absent, grub.cfg in
memdisk shall defer to usqwerty as the default keymap
grub_scan_disk: grub.cfg looks for cbfs file "scan.cfg"
and sources that if found, which will be inserted with
the string: set grub_scandisk=setting_goes_here (based
on target.cfg, generated by build/boot/roms automatically).
If no scan.cfg is found, it defaults to "both"
The "background.png" file remains unchanged, and present in
CBFS, used by grub.cfg if present (and it is, by default)
This change actually *saves* space in CBFS, due to compression,
and means that the grub.cfg is now compressed heavily. This
is also safer, because now the user overrides grub.cfg by
adding it, and they can still add grubtest.cfg for testing
first. If they accidentally delete both configs from cbfs,
Libreboot will fall back to the one in memdisk which would
presumably not be deleted.
This also means that lbmk can now more easily be used by
other build systems, that just want the GRUB part to re-use
in their own project. For example, people who want to build
custom coreboot images without using Libreboot's build system.
This change also *speeds* up the build process considerably,
on the parts where ROM images are copied. It's less than half
a second now, whereas previously it took about 30-45 seconds
for ROM images to copy, because of grub.elf being re-added in
each ROM via cbfstool, where compression is used; I believe
the compression part is what caused slowness.
Much, much faster, more versatile builds.

this was an oversight, in a previous commit.
there was a space, between variable name and
the equals sign, and then another space, so it

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.
