a tree can specify:
tree_depend="treename"
this will make the other tree be downloaded. this is
used for coreboot trees, to ensure that dependency
trees are downloaded, because trees can now re-use
crossgcc from other trees.

u-boot doesn't use submodules, so there's no point in
checking for it. now we can do with just one call to
the git submodule command, for simplicity
also, general code cleanup in this file (minor code
formatting improvements)

the directory is checked for deletion, but it's already
checked before download, to see whether it already exists.
lbmk already exits with zero status if the directory exists,
so the check is pointless (in this function)
also, general code style/formatting cleanup

the patchfail variable was only needed in the old design,
where git am was being handled inside a subshell, and
also when we did it directly in the target directory
without using a temporary directory. with the current
design, we can just call err() and ditch the tmp repo

there isn't really a problem right now, but a desired
and implemented behavioural change was that patches are
to be applied *before* updating submodules. well, the
previous commit reversed this change, under certain
conditions, such that submodules were applied first.
this patch fixes it, so that patches are done first.

right now, if we want to patch a project such that certain
submodules are no tdownloaded, or diffreent submodules are
downloaded, or current ones are downloaded from other
locations, we cannot do this, because we apply submodule
updates *before* applying patches.
therefore, we should change it so that they are applied
*after* installing patches.

while seemingly pedantic, this does actually make code
easier to read. mostly just switching to shorthand for
variable names, where no expansions or patterns are used

lbmk didn't quote certain arguments in commands, or
used ! -z instead of -n, things like that. simple fixes.

most of these are probably redundant, and will never
be called, but lbmk needs to be as safe as possible
under fault conditions. fail early, fail hard.

update/trees wasn't correctly returning non-zero status,
even though it was printing an error message, when git-am
failed. this is due to the way subshells work, and it was
overlooked in previous auditing.
additionally: don't directly copy trees to the destination,
instead patch/reset first, then copy only under normal
condition, just as with single-tree projects.
when running build/roms, the script would continue after
a bad git-am, without exit. this patch fixes it in the
most paranoid way possible. i'm now fairly confident that
lbmk will fail gracefully and efficiently, under error
conditions. this should prevent bad image builds.

only fetch if .gitmodules exists
in some cases, lbmk is compiling source trees that
use submodules, without having downloaded them first.
in all cases, those submodules are either optional,
or the build system auto-fetches them (or if it can,
we sometimes disable it as with grub and gnulib).
this is a nice fallback behaviour, for situations where
we forget to put submodules as dependencies under
config/git (and disable submodules in the given project).
with this change, release archives are guaranteed to
be complete, sans crossgcc downloads in coreboot; this
will be handled in a follow-up commit.

in some cases, use of x_ or xx_ can be error-prone,
due to the way $@ is handled; commands requiring
quotes, or with funny file names as arguments such
as spaces in the file name, or other special
characters, can make the x/xx functions break.
in those cases, where x/xx must not be used, the
commands use || err instead
in other cases, use of x/xx is superfluous, and has
been removed in some commands.

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!

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

do not update them in project/repos - despite what

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.

This is done recursively, with the following rule:
files first, then directories.
Where all patch files are applied from within the
patch directory, subdirectories (within the patch
directory) are then tried in alphanumerical order.
Then, within each subdirectory tried, the same rule
is once again applied. This is done recursively,
until every patch file is applied.
The code no longer applies *.patch, but instead any
file. Additionally, symlinks are avoided.
