Simon McVittie 2aed100945 Add 'subprojects/libglnx/' from commit '202b294e6079e23242e65e0426f8639841d1210b'
This makes the flatpak project more self-contained, and would have
avoided the problems we encountered with unintended changes in the
1.14.7 release. See <https://diziet.dreamwidth.org/14666.html> for an
opinionated description of some of the problems with submodules.

If we can eliminate submodules altogether, then it will become possible
to build Flatpak from a simple `git clone` or `git archive`, or from the
source tarballs auto-generated by Github (which are equivalent to a `git
archive`), without needing an extra step to populate the submodules. As
well as reducing the support burden from users periodically complaining
that our source releases are incomplete, this is a useful "nothing up
my sleeve" mechanism to make it easy to verify that our source releases
do not contain malicious changes hidden in vendored or generated files,
like the one that made CVE-2024-3094 possible.

Added with:

    git remote add --no-tags libglnx https://gitlab.gnome.org/GNOME/libglnx.git
    git fetch libglnx
    git subtree add -P subprojects/libglnx 202b294e60
    git commit --amend -s

To compare with upstream:

    git remote add --no-tags libglnx https://gitlab.gnome.org/GNOME/libglnx.git
    git fetch libglnx
    git diff HEAD:subprojects/libglnx libglnx/master

After checking the diff, updates can be merged into this project with:

    git subtree merge -P subprojects/libglnx libglnx/master
    git commit --amend -s

The commit merged here is the same one that was previously a submodule.
A subsequent commit will update it to the latest version of libglnx,
demonstrating how to review such updates.
