instead of using lots of if/else conditions, do that once
and set a variable, dry, to :
if not doing a dry run, the variable is empty. prefix this
variable in places where you don't want a certain action to
be performed, on dry runs.
more specifically, : does *nothing* and always returns with
zero status (success).
this results in cleaner code, and a small sloccount reduction.

otherwise, due to the idiosyncratic nature of the coreboot
build system, the coreboot.rom gets wiped out.
cbutils is still handled by premake. ensure that payloads are
only inserted just after running the coreboot make command.

-d does the same as -b, except for actually building
anything! in effect, it does the same as -f (fetch)
except that the resulting variable assignments will
not be recursive (as with -f).
if -d is passed, configuration is still loaded, defconfig
files are still cycled through, and more importantly:
helper functions are still processed.
the grub, serprog and coreboot helper functions have
been modified to return early (zero status) if -d is
passed.
this behaviour will be used to integrate vendor.sh
logic in with the trees script, for cases where the
user wants to only handle vendor files. e.g.:
./update trees -b coreboot x230_12mb
this would download the files as usual, build coreboot,
with those files, and then build the payloads. but:
./update trees -d coreboot x230_12mb
this would download the files, NOT build coreboot, and
NOT build the payloads.
this change increases the sloccount a bit, but i'm relying
on the fact that the vendor.sh script already re-implements
config handling wastefully; the plan is to only use trees.
for now, simply stub the same ./vendor download command.
there is one additional benefit to doing it this way:
this method is *per-kconfig* rather than per-target.
this way, one kconfig might specify a given vendor file
that is not specified in the other. although the stub
still simply handles this per target, it's done in premake,
which means that the given .config file has been copied.
this means that when i properly re-integrate the logic
into script/trees, i'll be able to go for it per-kconfig.
the utils command has been removed, e.g.
./update trees -b coreboot utils default
the equivalent is now:
./update trees -d coreboot default
this would technically download vendor files, but here
we are specifying a target for which no kconfigs exist;
a check is also in place, to avoid running the vendor file
download logic if tree==target
the overall effect of this change is that the trees script
no longer contains any project-specific logic, except for
the crossgcc build logic.
it does include some config/data mkhelper files at the top,
for serprog and coreboot, so that those variables defined in
those files can be global, but another solution to mitigate
that will also be implemented in a future commit.
the purpose of this and other revisions (in the final push
to complete lbmk audit 6 / cbmk audit 2) is to generalise as
much logic as possible, removing various ugly hacks.

stub it from the trees script. the way it works now,
there is less code in the build system.
./build roms
this is no longer a thing
./build roms serprog
this is also no longer a thing. instead, do:
./update trees -b coreboot targetnamehere
./update trees -b pico-serprog
./update trees -b stm32-vserprog
the old commands still works, which causes the new
commands to run
coreboot roms now appear in elf/, not bin/, as before,
but those images now contain payloads.
NOTE: to contradict the above: ./build roms is no
longer a thing, in that it's now deprecated, but
backward compatibility is present for now. it will
be removed in a future release.
./build roms list also still works! it will do:
./update trees -b coreboot list
also:
./update trees -b grub list
this is now possible too
if a target "list" is provided, for multi-tree sources,
the targets are shown.
there is another difference: seagrub roms are now seagrub_,
instead of seabios_withgrub.
seabios-only roms are no longer provided, where grub is also
enabled; only seagrub is used. the user can easily remove
the bootorder file, if they want seabios to not try grub first.

some of the variables only initialised in git.sh are
also used in the trees script, which is technically ok
because git.sh is included from the trees script, but
it makes more sense to declare them in the latter.

when downloading multi-tree projects, the rev can be reset
to HEAD instead of the actual rev for a given target. this
occurs when the bare repo (e.g. src/coreboot/coreboot) does
not exist and has to be downloaded first.
bare repository downloading does not rely on target.cfg, in
this context, only pkg.cfg, but it uses the same variable
names (e.g. "rev").
instead of using a separate variable name, thus increasing
code complexity (which is the exact opposite of what i want
to do), do the bare repository download first.
this means that the git.sh script is much cleaner now, for
multi-tree projects, in that it *only* copies the bare repo
then runs git_prep; in that context, the bare repo is cloned
directly by calling the relevant function from script/trees,
which is the same behaviour as when cloning single-tree
project sources.

the same function that loads configurations for single-tree
projects has been merged with the function for multi-tree
configs in git.sh, and that functionality has been removed
from git.sh; now it is all unified in the trees script.
as the saying goes: write one program to do one thing well.
the purpose of git.sh is to download source code, but not
to handle configuration files; the latter is meant to be
handled by the trees script, which then calls into git.sh
before running the build logic for that given project.
additionally: the "seen" files are no longer handled, at all.
the logic there was added ages ago, because at the time, i was
considering whether to separate configuration into a new
repository, so that users could more easily make their own
configuration, so it was a guard against misconfiguration.
however, that decision was canceled and we're always very
careful not to introduce a loop; if a loop does occur, the
worst that can possibly happen is you waste some CPU cycles.
Instead, print (on standard output) what config file is being
used, so the operator can see when an infinite loop occurs.
ALSO:
remove _setcfgarg in load_project_config()
it was used to skip when a target.cfg file didn't exist,
specifically on single-tree projects, but this is now
handled using -f instead, on the while loop inside that
function, so _setcfgarg is now a redundant variable.

this is over-engineering, because we do not allow just
about any path to be provided; it's not provided as an
argument in a command, for example.
this is dictated by a configuration file, which we control.

we don't need to check whether the binary exists, because
make already does that for us.
we still need to check that the directory exists, because
older versions of coreboot did not include kbc1126, and we
do still use older coreboot revisions on some boards.

if injection is attempted, verification comes next,
and verification fails.
this happens for kcma/kgpe amd boards, where pike2008
fake roms are inserted by inserting the correct pci
ids using /dev/null as a source. an empty pike2008 rom
prevents seabios from loading the real pci rom, and this
is done because the real one hangs SeaBIOS.
a similar fix was made for ./vendor download, but
overlooked for ./vendor inject. this patch fixes that.

testing +x is all well and good, but the variable string
may be empty, even if set. some of the checks in the build
system are relying on the latter, so handle it.
