it's just two lines, and we want much more granular
control of where the lock is enforced. it should be
JUST after confirming that the instance is a parent.
it is at this moment that we should bail if a lock
file exists, because this signals that another instance
of xbmk is running.

don't update them on child instances, since it's a waste
of time; the lock file prevents further execution, so we
are just wasting time writing to disk.

we don't need to read or write a file at all, in that case.
we only then need to generate one if running ./mk release.
the scenario in which no .git and no version files exist
is when someone grabs the build system from a snapshot
generated by e.g. forgejo instances. it's ill advised, so
we advise against it, but it is mitigated in code.

That way, unnecessary work is avoided on child instances.
Of course, the current check assumes that TMPDIR wasn't
already set by a wily user before running lbmk, but then
those sorts of users probably know what they're doing.
If they don't know, they will soon find out. Therefore, I
have added additional checks on child instances, preventing
the build system from running if XBMK_CACHE is not set; if
it isn't, then that could very easy lead to certain system
files being overwritten.
The user must never know what happens if XBMK_CACHE is unset.
We simply will not allow it.

this way, initialisation will not be performed erroneously
while another parent instance of lbmk is running.
Signed-off-by: Leah Rowe <leah@libreboot.org>
This is earlier than the current check, thus preventing
the initialisation of a git repository and/or the recreation
of xbmktmp and xbmklocal by erroneous parent executions of lbmk
while another parent is running - the latter of which could have
caused a massively unpredictable build failure, so this is also
a pre-emptive bug fix, fixing all kinds of weird bugs.

we really only need it there, because the context is
for release archives. normal use of the git repository
doesn't matter in the context of deletions, because that
will not be distributed. only the result of ./mk release
will be distributed.
the builds produced will not change as a result of this,
for people using the normal git repository, because the
files in question are never used anyway, in our configs.
this is being done to make working on local repos easier.

On release archives, I overlooked the previous change to
downloads, during the recent implementation of extra safety
checks. I previously checked there whether the variable named
CONFIG_KBC1126_FIRMWARE was defined, and grabbed both; now I
check CONFIG_KBC1126_FW1 and CONFIG_KBC1126_FW2 separately,
grabbing each file separately.
This patch replicates that change for insertions. Otherwise,
hash verification on ROM images will fail, when running the
inject script on release images.
Downloading was being done, reliably, and the extracted files
were correct, so there was no danger if the user was building
from source and flashing that way.
However, checksum verification on full images failed when
inserting into archives. This is not because the files were
wrong; they were *correct*. However, the EC firmware was not
being inserted *at all* on HP EliteBooks, because of this
oversight. The check is now based on whether the paths to
the files themselves are defined, not whether EC firmware
is enabled in the coreboot config; the latter is implied.
With this patch, vendor file insertion once again works
perfectly, without error, on every board. There was no real
danger for users, just a minor inconvenience. Sorry!

the exit from mkdst can also be non-zero if mv or cp
failed, but there's no way to handle that reliably.
therefore, the checksum verification should be done
one final time, to compensate.

I currently check the downloaded files e.g. .exe file, but
then I don't check - or even define - sha512sums for the
files extracted from them e.g. me.bin
This patch fixes that. It also caches the hashed files, so
that extraction is faster on a re-run - this makes release
builds go faster, when running ./mk release
If a checksum is not defined, i.e. blank, then a warning is
given, telling you to check a specific directory. This way,
when adding new vendor files, you can add it first without
specifying the checksum, e.g. me.bin checksum. Then you can
manually inspect the files that were extracted, and define it,
then test again.
In a given pkg.cfg for config/vendor, the following variables
are now available for use:
FSPM_bin_hash for fsp m module
FSPS_bin_hash for fsp s module
EC_FW1_hash for KBC1126 EC firmware (1st file)
EC_FW2_hash for KBC1126 EC firmware (2nd file)
ME_bin_hash for me.bin
MRC_bin_hash for mrc.bin (broadwell boards)
REF_bin_hash for refcode (broadwell boards)
SCH5545EC_bin_hash for sch5545 firmware (Dell Precision T1650)
TBFW_bin_hash for Lenovo ThunderBolt firmware (e.g. T480/T480s)
E6400_VGA_bin_hash for Dell E6400 Nvidia VGA ROM
In practise, most people use release archives, and the
inject script, so I knew those were reliable, because the ROM
images were hashed prior to removing files. This patch benefits
people using lbmk.git directly, without using release files,
because now they know they have a valid file e.g. me.bin
Previously, only the download was checked, not the extracted
files, which meant that the only thing preventing a brick was
the code not being buggy. Any number of bugs could pop up in
the future, so this new level of integrity will protect against
such a scenario, and provide early warning prompting bug fixes.

in a few places, we use the presence of a file found
by fx_ to cause an exit, but the command that runs
looks something like:
exit 1 "string"
this yields an error, and a non-zero exit, because of
too many arguments to "exit", but we wanted a non-zero
exit anyway.
nevertheless, this is incorrect.
to fix it, eval is used instead. if the never-going-to-exist
condition one day exists where exit 1 actually returns, not,
you know, exits, we will use err instead, with the string
as argument.
this should be fine. it's a bit hacky, but so is fx_, and
it works. fx_ is used in several places to keep the sloccount
down, providing a common way to perform while loops on the
output of a command; that is its only purpose..

We already do what the old code does in setcfg, by
