git.sh: support downloading files as submodules when we download coreboot, we currently don't have a way to download crossgcc tarballs, so we rely on coreboot to do it, which means running the coreboot build system to do it; which means we don't get them in release archives, unless we add very hacky logic (which did exist and was removed). the problem with coreboot's build system is that it does not define backup links for each given tarball, instead relying on gnu.org exclusively, which seems OK at first because the gnu.org links actually return an HTTP 302 response leading to a random mirror, HOWEVER: the gnu.org 302 redirect often fails, and the download fails, causing an error. a mitigation for this has been to patch the coreboot build system to download directly from a single mirror that is reliable (in our case mirrorservice.org). while this mitigation mostly works, it's not redundant; the kent mirror is occasionally down too, and again we still have the problem of not being able to cleanly provide crossgcc tarballs inside release archives. do it in config/submodules, like so: module.list shall say the relative path of a given file, once downloaded, relative to the given source tree. module.cfg shall be re-used, in the same way as for git submodules, but: subfile="url" subfile_bkup="backup url" do this, instead of: subrepo="url" subrepo_bkup="backup url" example entries in module.list: util/crossgcc/tarballs/binutils-2.41.tar.xz util/crossgcc/tarballs/gcc-13.2.0.tar.xz util/crossgcc/tarballs/gmp-6.3.0.tar.xz util/crossgcc/tarballs/mpc-1.3.1.tar.gz util/crossgcc/tarballs/mpfr-4.2.1.tar.xz util/crossgcc/tarballs/nasm-2.16.01.tar.bz2 util/crossgcc/tarballs/R06_28_23.tar.gz the "subrev" variable (in module.cfg) has been renamed to "subhash", so that this makes sense, and that name is common to both subfile/subrepo. the download logic from the vendor scripts has been re-used for this purpose, and it verifies files using sha512sum. therefore: when specifying subrepo(git submodule), subhash will still be a sha1 checksum, but: when specifying subfile(file, e.g. tarball), subhash will be a sha512 checksum the logic for both (subrepo and subfile) is unified, and has this rule: subrepo* and subfile* must never both be declared. the actual configuration of coreboot crossgcc tarballs will be done in a follow-up commit. this commit simply modifies the code to accomodate this. over time, this feature could be used for many other files within source trees, and could perhaps be expanded to allow extracting source tarballs in leiu of git repositories, but the latter is not yet required and thus not implemented.

define mdfiles/images in config/submodules/docs/ again: the "depend" variable must never be used for subprojects that point to a subdirectory of the main project, because there's no clean way of handling this in case of error conditions. make it a submodule under config/submodules/. this is for the documentation, including static site generator documentation, and image files (photos). as of this revision, there are now only those "depend" projects defined in config/git/, where the destination directory of the subject is not a subdirectory of the main project, so: in a subsequest revision, i will mitigate an existing bug whereby failure of the dependency project leaves the main one still intact, breaking builds; this revision enables that to be done. from now on, subproject-to-subdirectory-of-main-project will be avoided in config/git/; config/submodules/ will be used.
