stable branches update

[Bruno Haible]

Hi,

I updated the branches stable-202201 and stable-202207 with the bug fixes
from the last three months.

Also, I created a new stable branch stable-202301.

The branch stable-202201 being one year old, it will no longer be updated.
Users of this branch are recommended to switch to stable-202207.
