prevent duplicate main instances of the build
system from running
the lock file is deleted when the parent process
exits, alongside the tmpdir deletion
the build system must only ever be run ot one
instance at a time, per work directory

instead, check for the presence of target.cfg files
not in config/project/ but config/project/tree/
the way this check is done, it merely returns 1 if
config/project/*/target.cfg is detected, and returns
0 in all other cases, even if config/project/target.cfg
exists
that way, if the maintainer accidentally adds a
target.cfg in the main directory, the given multi-tree
project will not break

this avoids writing the version/versiondate files as root.
this complements the previous fix, that avoided writing those
same files when running the dependencies command.
initial setup of the build system requires root, to run the
dependencies script, but otherwise the build system prevents
running as root for everything else, so we must avoid writing
the version/versiondate files as root.
that same avoidance is necessary when checking whether running
other commands as root; ironically, this check then prevented
running the build system at all!
the bug should be fully fixed now. i found this quite by accident
the other day, when testing something else.
good thing this got fixed because the release!

do it strategically, in just the right place so that the
version and versiondate files aren't written.
otherwise, version/versiondate are written as root and
the build system becomes unusable after that, unless you
reset the file ownerships from root. hardly user-friendly.
mitigate this bug.

adding help again is a bad idea. code should never
document itself; that's what documentation is for.
so, make the code do a better job telling the user
where to find documentation.

The build system already deletes .git in all source
directories for each given release, but does so at
the very end; it still does, but now it is deleted
one by one per project, to save space during very
large builds (release sizes vary wildly, depending
on how many trees exist for coreboot basically).
If you're building entirely in tmpfs (as I do), this
could be a problem if you have lots of .git/ directories.
This change reduces disk usage, or in the above example,
memory usage when running the build system from tmpfs.
This complements another recent change, where ROM images
are compressed per target during release builds, rather
than all at the very end of the process. It is part of a
series of optimisations, to reduce the memory and disk
usage of the build system, and to reduce I/O wastage
in general.
This change will not be the last of such changes!

when running the inject logic, we should still initialise
the git repository because these commands make use of the
coreboot build system which requires git.

an equivalent change has been made in cbmk.
certain lbmk-specific variable names have been made
generic, with certain functions and other variables
moved around.
i maintain sync between libreboot and canoeboot, where
both projects can have the same behaviours, and most of
the merge conflicts have to do with variable names
containing "LBMK", "lbmk", "cbmk" or "CBMK", or
indeed "canoeboot" and "libreboot"
LBMK/lbmk/CBMK/cbmk variables between canoeboot and
libreboot now contain the string XBMK/xbmk
it should now be *much* easier to merge build system
changes between lbmk and cbmk.

i always say, code should never document itself.
that's what documentation is for. the releases
contain documentation under docs/ but the git
repository does not; for that, use the website.
(in practise, lbmk usually needs internet anyway)

it's a pointless feature, initially added just to one-up
gnuboot and only intended for canoeboot, to provide u-boot
tarballs with deblobbing. this was done, because the parabola
build system has certain limitations so the idea is to provide
them with tarballs. but why? they can just fix their build system...
delete this bloat from lbmk. we only need to provide full sources,
and rom images.

this function is not needed, because it's only called
once and it's very small.
furthermore: insert_version_files does ntot need to be called here,
because they same files are generated immediately afterward when
running that version of lbmk.

export LBMK_RELEASE="y"
if this is done, the tarball is created instead
of a directory, and the rom images are nuked using
./vendor inject with the nuke option, inserting the
correct version files; the rom directory is deleted
now the release script logic simple renames existing
tarballs. the benefit of this change is fewer lines of
code, and now lbmk doesn't use an insane amount of disk
space when building a *lot* of release images (the
uncompressed directories are deleted after each build)

the release variable is all we need, turning a target on
or off for a given release.
the status checks were prone to bugs, and unnecessary; it
also broke certain benchmark scripts.
it's better to keep the lbmk logic simpler. board status
will be moved to the documentation instead.

there are only two scripts under script/ now, and there
probably won't be many more. lbmk's design has simplified
to such a degree that the two-level directory structure is
no longer necessary.
the existing command structure has not changed. for example:
./build roms list
./update trees -f coreboot default
these will still work, but the symlinks to "build" are now
strictly for backwards compatibility; they may be removed
at a later date, but i'll keep the current design for now.
this also leads to a quirk, for example:
./build roms all
./update roms all
these now do the exact same thing, whereas "./update roms all"
would have previously been an invalid command.

the main script isn't that big, and since the main
purpose of lbmk is geared toward the releases, it
makes sense to reduce the number of scripts by
merging into the main one
the way this works, "./update release" still works
afterward
so, the way lbmk is used shall remain unchanged

this is a follow-up to the previous commit
again, there's no posix way to check the path to the
file at argument 0, because readlink (utility) isn't
defined in posix (the C function is defined, but not
the utility included on many unices)
check whether "build" (file) exists, and whether it
is a symlink; if the latter, then we are definitely
not in the lbmk work directory!

there's no portable(posix) way to check when running
from a symlink to lbmk in the current work directory
for example:
ln -s lbmk/build lbmktest
./lbmktest roms list
this would pass the new test, and first try to
include option.sh. in practise, the user probably doesn't
happen to have include/option.sh in their current path
i can use readlink here, but again not portable
the current check will suffice. it also works when
the symlink is called from $PATH
e.g. /usr/bin/lbmktest exists and you do:
lbmktest roms list

LC_COLLATE and LBMK_RELEASE are important variables. we want
to make sure that these are seen by everything.

accomplish just that.

lbmk sets TMPDIR to /tmp, and then creates a tmpdir, then
exports *that* as the value of TMPDIR. this unified TMPDIR
location then contains all subsequent files and directories,
when any script or program makes use of /tmp, via mktemp. at
least, that's the theory!
in practise, because it was only being properly exported from
the main build scripts, subscripts that are then called were
not exporting it, at least that is my assumption because in
some cases, i found that the coreboot build system was leaving
errant files behind outside of our own TMPDIR, and that build
system did not seem to be setting TMPDIR itself; more debugging
is needed.
anyway: use the exact same logic, but do it from err.sh. since
err.sh is included from every lbmk script, that means it will
always be exported when running every single part of lbmk. this
should reduce the chance that mktemp creates files and directories
outside of our custom TMPDIR location.
this is because in lbmk, we mitigate unhandled tmpdirs/files by
unifying it in the manner described, then deleting the entire
TMPDIR on exit from the main lbmk parent process (the main
script that the user called from, which is always the "build"
file).
in lbmk, effort is made to clean up temporary files properly,
without relying on this catch-all, but we can't rely on that.
the catch-all should also be as robust as possible.
