if you copy a symlink, you create a whole new file with the
contents of what that symlink points to.
what we need to do instead is re-create the symlinks. this
is relevant for all symlinks to the main lbmk script, from
the main directory of lbmk.git.
this avoids there being multiple copies of the main lbmk
script, in release archives.

in some cases, messages that should be considered errors
or warnings, were being written to the standard output,
rather than written as error messages.
also: one or two printf statements should specifically
avoid printing errors (to any file); in these cases,
stdout has been redirected to /dev/null

these scripts used to be in the main directory of
lbmk, and thus needed to check for root user, and
also git credentials. now they are called by the main
lbmk script, which also runs the same checks.
avoid waste of resources by not running the same
check twice.

on e6400_4mb, the release build scripts remove nvidia's vga
rom which is used on dgpu models. however, microcode is also
removed in separately copied rom images
the inject script was inserting vgaroms directly into these
no-microcode roms, but the microcode blob is bigger than the
vga rom, and cbfstool inserts into the first available free
spot within cbfs, so it was inserting into the spot where
cpu microcode went. this caused the rom checksum to not match
what was generated during build/release/roms being executed
the only real fix is to guarantee offsets within cbfs for all
files, by recording what offsets were used and then calculating
that during insertion
so this patch is a workaround, but fixes the issue. the workaround
is: don't insert blobs directly on no-microcode roms, instead
insert only on microcode-based roms, then re-copy those roms
and remove microcode in aptly named copies
it's a bit more convoluted, but works perfectly fine.

sha-1 has known collision issues, which may not be readily
exploitable yet (in our context), but we should ideally use
a more secure method for checking file integrity.
therefore, use sha-2 (sha512sum) for checking files. this is
slower than sha-1, but checksum verification is only a minor
part of what lbmk does, so the overall effect on build times
is quite negligible.

Tested on a Nucleo-F042K6.
That has an onboard stlink:
`st-flash --format ihex write bin/serprog_stm32/serprog_nucleo-f042k6.hex`
The usb port used for flashing is separate, its is exposed on
the pin header instead. Check boards/nucleo-f042k6.h for usb pinout.

where it is set to "both" (grub_scan_disk), inserting
scan.cfg is superfluous, because grub.cfg defaults to
both anyway, unless otherwise specified by scan.cfg,
and only if that file exists within cbfs.
thus, save a bit of build time (only a slight saving)

target.cfg can now specify e.g.
grub_timeout=20
this would then be inserted as timeout.cfg in cbfs,
containing the instruction:
set timeout=20
HP laptops need a bit of extra time, due to the delay
caused by the EC bug workaround deployed in GRUB
desktops in general need extra time. this too is set to
10s, like the HP laptops.
only insert timeout.cfg if actually needed (declared in
target.cfg), otherwise grub.cfg will default to 5s

My previous patch b0rked memtest and others because when making sure
their parent directory (the project root) exists, it would instead create
the project directory (memtest86lus). The later move would then put the
git repo inside that (memtest86plus/memtest86plus_123456).
We just need to make sure we don't create the target directory itself.
This way, there's no need to hardcode any project names.
Tested by ./updating rpi-pico-serprog, memtest86plus, grub and seabios.

we must conserve memory usage, in the event that the
user's /tmp is a tmpfs. copying of ROM images into
tmpfs is ill advised; we must copy them, due to how
the release process works (e.g. stripping of blobs,
but this must be done in a way so as to not interfere
with regular builds, thus they are copied instead)

the /tmp/ file system may be a tmpfs, with conservative
memory limits, depending on host system.
it's more likely that the user will have enough disk space
under tmp/ within lbmk (if they don't, they can't use
lbmk anyway). that is to say: more likely that they would
have the disk space, but not the memory.

it doesn't really make sense for them to be under
blobs/ - nominally, they are blobs, but they are
well-understood data files containing config data,
that is easily parsed by tools like ich9show or
ifdtool (and tools like bincfg or nvmutil)
blobs/ has been re-purposed: this directory no longer
exists in lbmk, but it is created (and on .gitignore)
when needed, by blobutil
thus, the blobs/ directory shall only contain vendor
files, and only those files that libreboot scrubs from
releases. therefore, build/release/src can (and has
been) simplified; it currently copies just the ifd and
gbe files from blobs/, selectively, and this logic is
quite error prone, requiring maintenance. now, the
build/release/src script simply copies config/ (which
only ever contains distributable files) and entirely
ignores the blobs/ directory
the blob download script already creates the required
directory, except for the sch5545 download; this is
now fixed
lbmk code size is slightly smaller, due to this patch

This cuts down on build time, and it will allow libreboot
to remove large chunks of code.
these ifd/gbe configs are just binary-encoded config files,
in a format well-understood. they can easily be opened up
and displayed, using ich9show or ifdtool, and manipulated
by these tools; bincfg can generate them from scratch, and
nvmutil can change mac addresses, for example.
so, do this and remove from lbmk the following:
* ich9utils (which contains ich9gen) - not needed anymore
* code in lbmk for handling ich9gen and insertions; the
coreboot build system is now used, for this same purpose,
so remove such code from lbmk
this results in a massive code size reduction (thousands of
lines) in lbmk; smaller when only looking at the build
system, but much larger when you consider that ich9utils
is also removed (about 3k sloc)

a follow-up patch will make use of these, rather than ich9gen,
and ich9gen will be deleted.
these files were in fact generated *by* ich9gen.
coreboot has ifdtool and bincfg, the latter of which can
generate both ifd and gbe files for ich9m. that, and nvmutil
which is part of libreboot, can change gbe mac addresses.
i was going to replace ich9gen with a script that would run
bincfg, ifdtool and nvmutil, to greatly reduce code size,
because ich9gen is about 3k sloc.
however, in practise we would always generate the same ifd
config, and basically only change the mac address if that's
what the user wants; nvmutil can already do that just fine.
so, just include the binaries directly.
