Barend Gehrels fc2652323b [buffer] refactor analysis of piece into shorter and slightly more efficient (few %) code.
It is now one function. In later commits we will extend this by checking helper
segments separately, which should also be more efficient.

It changes one test-case, probably because ofn ear_offsetted. The change is not visible
and the result is probably more correct. SQL Server reports this polygon as invalid.
