Tracking repository for unnamed-sdvx-clone

We have to track patches for unnamed-sdvx-clone here because the upstream repo uses submodules.

Standard Operation Procedure

1. Fetch the desired tag from unnamed-sdvx-clone (e.g. git fetch https://github.com/Drewol/unnamed-sdvx-clone.git v0.6.0).
2. Switch to FETCH_HEAD (git checkout FETCH_HEAD).
3. Recursively update submodules (git submodule update --init --recursive).
4. Recursively remove .gitattributes files, .gitignore files, .gitmodules files and .git directories except the one in the top-level (find . \( -name .gitattributes -o -name .gitignore -o -name .gitmodules \) -delete; find . -name .git, note that .git directories have to be manually removed).
5. Remove the subproject attribute of submodule folders from git (git submodule | awk '{print $2}' | xargs git rm --cached).
6. Update the index using all files in the entire working tree (git add -A).
7. Make a soft reset to the tarball branch (git reset --soft tarball).
8. Redo step 6, then create a new commit with message of chore: import v$VER (git commit -m "chore: import v$VER").
9. Create a lightweight tag with name of v$VER (git tag "v$VER").
10. Push the tarball branch and the tag just created to the remote (git push; git push --tags).
11. Create a new branch with name of aosc/v$VER, pointing to the current HEAD, then switch to it (git checkout -b "aosc/v$VER").
12. Apply all needed commits and/or patches.
13. Create a lightweight tag with name of aosc/v$PKGEPOCH%$PKGVER-$PKGREL (git tag "aosc/v$PKGEPOCH%$PKGVER-$PKGREL"). If any of these variables equals zero, omit the related section and the corresponding separator. For the definition of these variables, refer to autobuild4.
14. Push the aosc/v$VER branch and the tag just created to the remote (git -c "push.autoSetupRemote=true" push; git push --tags).
15. Prepare patches for the ABBS tree (git format-patch "tags/v$VER..tags/aosc/v$PKGEPOCH%$PKGVER-$PKGREL").
