So here's the first patch containing a few hundred (!!!) implementation-agnostic overlay tests. I took all Lisp-level overlay related tests in the feature-noverlay branch, removed automatically generated ones and a single test that was aware of the tree-based implementation. This should be a good basis for any further work related to overlays (and buffers in general). I did not add a single line of code, all credit goes to Andreas. Feel free to request tweaks and additions. Note that I am still in the process of pushing the papers through corporate bureaucracy. No problems, I got all the approvals needed but it'll take a week or two more.
