It took a while, but I am finally done with rebasing the org-fold branch code onto current main. This branch has been tested by me and other volunteers for over a year. Things are basically stable using recent Emacs versions. There were a couple of back-compatibility issues with older Emacs, which I fixed during the cleanup. Those may need to be tested more carefully after merging to main.
I would like to thank all the people who helped with bug reporting and provided bugfixes over the testing time. Thank you all - arkhan, HyunggyuJang, Robert Irelan, Alois Janíček, Anders Johansson, Daniel Kraus, Ypot, ntharim, Colin McLear, Yiming Chen, tpeacock19, and Karl Voit. After the cleanup, some patches are not included for the merge. Apart from my patches, 3 patches by Anders Johansson are included here. He has signed FSF copyright paperwork and appears on the Org mode contributor list (https://orgmode.org/worg/contributors.html). Unless there are comments on the patches below, I plan to merge the branch in the coming weeks. Please, let me know if I still need to wait for comments.
