Just one script.

Just one!

Well, two, but the 2nd one already existed:
logic in update/project/trees and
update/project/repo was merged into
include/git.sh and update/project/build
was renamed to update/project/trees; an -f
option was added, which calls the functions
under git.sh

so git clones are now handled by the main build
script (for handling makefiles and defconfigs)
but the logic there is a stub, where git.sh
does all the actual heavy lifting

this cuts the file count down by two, and reduces
sloccount a reasonable amount because much of
the logic already exists in the build script, when
it comes to handling targets. git.sh was adjusted
to integrate with this, rather than act standalone

build/release/src was partly re-written to accomodate this

memtest86plus was patched to have a central Makefile, and
lbmk modified to use that, rather than mess with build32
and build64. the central Makefile just builds both targets
or cleans both targets

Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.

Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.

This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.

update/blobs/download and update/project/repo both use
the same logic, for setting variables with awk and a
specially formatted configuration file.

unify this logic under include/option.sh, and use that.

With this change, lbmk now also updates submodules on
simple git clones, not just multi-tree clones.

This is OK, because git does not return non-zero status
when git submodule update is ran, where git submodules
are not actually defined.

Handle patches by a function at include/git.sh

This results in much cleaner copyright and license declarations.
SPDX headers are legally recognised and make auditing easier.

Also, remove descriptions of each script, from each script.
Libreboot documentation at docs/maintain/ describes them.

With this change, it's still possible to have a single
file at config/git/revisions, but this has been scrapped.

Instead, multiple files now exist under config/git/ with
the same modules declared, but the files are separated
logically. List of files under config/git:

* bios_extract
* biosutilities
* coreboot
* flashrom
* grub (gnulib also defined here)
* me_cleaner
* memtest86plus
* seabios
* serprog (multiple projects defined)
* u-boot
* uefitool

The rationale behind this change is simple: in the future,
we will stop relying on build systems within imported
projects for the import of git submodules. Instead, we
will handle them directly in lbmk.

Additionally, a Linux payload is planned for Libreboot, made
easier by the recent audit (script handle/make/config makes
it easy to integrate Linux, and handle cross-compilers for
userland utilities); a "linux" file under config/git/ could
also define rules for each project besides linux, such as
musl libc, busybox and other utilities.

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.
