as opposed to the current 3-level structure.

recent build system simplifications have enabled
this change, thus:

./build fw coreboot -> ./build roms
./build fw grub -> ./build grub
./build fw serprog -> ./build serprog
./update project release -> ./update release
./update project trees -> ./update trees
./update vendor download -> ./vendor download
./update vendor inject -> ./vendor inject

alper criticised that the commands were too long,
so i made them shorter!

move it all to other files where items are used, and not
used anywhere else. this reduces the size of vendor.sh.

also remove a few redundant variables, or variables that
are not meaningfully used.

a few items have been moved to include/option.sh

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

./build boot roms is now: ./build firmware coreboot

./build fw serprog is now: ./build firmware serprog

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.

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.
