XBMK_CACHE is now used, instead of hardcoding cache/
this is exported initialised to cache/, if unset.
this means you can set your own directory, and it means
./update release will use the same directory.
this means bandwidth wastage is further avoided.

a previous change made it more redundant, falling back
on old behaviour (direct downloading, not cached), but
the way it's done means that the function never returns
an error condition in practise.
this patch fixes it.

lbmk must still define payloads, but specific configs
may use coreboot's build system instead.
you might use this to add your own config with, say,
tianocore payload, using coreboot.git to build it,
rather than using lbmk's choice of payloads.

lib.sh download() is used by subfile handling in git.sh,
e.g. crossgcc tarballs.
they are not currently cached, but are downloaded directly
in place.
cache them, under cache/file/, saved with the name equal
to the checksum, so: cache/file/CHECKSUM
if the given cached file exists, use it as-is for simple
copy, instead of curl. this avoids re-downloading a lot of
crossgcc tarballs, where different coreboot trees may use
some archives that are the same throughout.

if doing a retry, the directory may still exist, which
would make git clone yield an error response; the existing
directory will have been the one that failed to reset, so
let's delete it.
the one deleted is not the cache (repo/PROJECT/), thus
otherwise maintaining current behaviour.

normally, a project is cached at repo/PROJECT/, and
cloned from there to the final destination.
errors lead to a calling of $err, but this will result
in a return if done from inside a subshell, of non-zero
value, so use this to re-try with a 6th argument when
calling tmpclone().
in most cases, this fallback will never kick in, but
it will kick in resetting or patching the cached clone
fails; specifically, we are interested in the reset part.
a given project name may change repositories in lbmk at
a given time. if this happens, and the old one is cached,
the overall result of this patch is that lbmk will fall
back to the old behaviour, where git urls are tried
directly, without caching.

actual source code is not scanned, but config directories are
scanned. simply get the checksum of each file under config/
pertaining to a given project/tree, and also for the given
target. coreboot utilities are also handled.
if it changes, in any way, delete and re-build automatically.
such deletions should probably still be done manually, as part
of understanding the build system, but this change should make
the build system much easier to use during development.

re-use repo/project/
this means that single- and multi-tree projects now
have a unified cached git repo location, as per the
new rules, thus saving on disk space usage.

do it based on the URL, e.g. https://review.coreboot.org/coreboot
becomes repo/coreboot
the downside is if you have two projects with repo urls specifying
the same string at the end, but this isn't the case at the moment
and likely won't be the case, but it's a theoretical issue.
this saves on bandwidth when downloading identical submodule repos
between multiple trees within the same multi-tree project
for example, coreboot 3rdparty/vboot is no longer downloaded more
than once, instead cloned locally on subsequent downloads.
if repo/DIR exists, git-pull is attempted, but errors do not result
in a non-zero exit, by design.

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

-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.
example usage:
./update trees -d coreboot x230_12mb
this would download the files, NOT build coreboot, and
NOT build the payloads.
there is one additional benefit to doing it this way:
the utils command has been removed, e.g.
./update trees -b coreboot utils default
the equivalent is now:
./update trees -d coreboot default
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.
