e.g. ./build boot roms list
./update blobs inject listboards
./build boot list
./build clean list

also this is now possible:
./build list
or maybe
./update list
^ would list directories in resources/scripts/build
and resources/scripts/update respectively

this script is added:
resources/scripts/build/command/options

call it like so, e.g.
./build command options resources/coreboot

this script is now used, for list functions in
other scripts.

lbmk is much more likely to crash now, in error conditions,
which is a boon for further auditing.

also: in "fetch", remove the downloaded program
if fail() was called.

this would also be done for gnulib, when downloading
grub, but done in such a way that gnulib goes first.

where calls to err write "ERROR" in the string, they
no longer say "ERROR" because the "err" function itself
now does that automatically.

also: listmodes/listoptions (in "lbmk") now reports an
error if no scripts and/or directories are found.

also: where a warning is given, but not an error, i've
gone through in some places and redirected the output
to stderr, not stdout

as part of error checks: running anything as root, except
for the "./build dependencies *" commands, is no longer
permitted and lbmk will throw an error

mrc downloads: debugfs output no longer redirected to /dev/null,
and stderr no longer redirected to stdout. everything is verbose.

certain non-error states are also more verbose. for example,
patch_rom in blobs/inject will now state when injection succeeds

certain actual errors(bugs) were fixed:
for example, build/release/roms now correctly prepares the blobs
hash files for a given target, containing only the files and
checksums in the list. Previously, a printf message was included.
Now, with this new code: blobutil/inject rightly verifies hashes.

doing all of this in one giant patch is cleaner
than 100 patches changing each file. even this is yet part
of a much larger audit going on in the Libreboot project.

this same change has been applied, selectively, to
certain return statements. the general rule is this:
the return statement should only be used to direct
logic within a script, where certain non-errors
states are used to skip certain actions; the exit
command should *never* be used to return non-zero,
except by err(). in so doing, we ensure easier
debugging of the build system

also: strip_rom_image in build/release/roms was
running "continue" when a rom file didn't exist,
despite not being a while/for loop. i make it
return (non-error condition) instead

it's ok for a script to exit 0, where appropriate,
but perhaps a function could also be written for it

include/err.sh

this new handling also does mundane things,
such as tell you what script b0rked

in update/blobs/download, i saw instances where
appdir was being deleted with rm -r, but the more
appropriate command would rm -Rf. this is now fixed.

other than that, i've mostly just simplified a bunch
of if statements and consolidated some duplicated
logic (e.g. if/else block for dependencies in
build_dependencies() of update/blobs/download

one or two functions and/or variables have been
renamed, for greater clarity in the code, also
removed a few messages that were redundant

used printf instead of echo, in a few places, also
fixed up the indentation in a few places

See file:
resources/scripts/build/defconfig/for
It is based on:
resources/scripts/build/payload/u-boot

The u-boot payload script has been deleted, as has the
seabios payload script; the build/boot/roms logic has
been heavily simplified too, by removing the logic for
building of elf files based on defconfig.

SeaBIOS, U-Boot and coreboot all use defconfig-type
infrastructure for their build systems, and they are
fundamentally the *same* in how to compile each codebase,
at least in an lbmk context, regardless of actual (and
very huge) differences in these codebases.

Several hundred sources-lines of code have been eliminated
by this change, drastically simplifying everything; U-Boot
payload compiling also now errors out when a single build
fails, instead of continuing. Also: build/boot/roms no longer
re-compiles a coreboot target that was already compiled,
which is the same behaviour observed for payloads.

(this means you must now manually delete a target, when you
wish to re-build it; the build/boot/roms logic now more or
less just runs cbfstool; blobutil is handled from
build/defconfig/for)

ALSO: Since crossgcc is now handled by build/defconfig/for, not
build/boot/roms, standalone compiling of u-boot is now possible.
This has been tested. You compile it like so:
./build defconfig for u-boot
or specific trees, e.g.
./build defconfig for u-boot default

One other consequence of this patch is that re-building the same
ROM image is now much faster, because the same builds are re-used
unless deleted. This could be useful when testing grub.cfg changes,
for example, if that's all you change. With things like ccache used
(not yet used robustly in lbmk), this could speed things up more,
depending on the codebase.

This patch demonstrates the raw power of lbmk; it is a very
simple and highly efficient build system, and now much more so!

it's bloat, and was only there for backwards compatibility
with the old commands, but the new commands are e.g.

./update blobs inject

instead of:

./blobutil inject

this results in a slight code size reduction in lbmk

will pass all args as a single arg, which is wrong
