Summary: The `lib/linelog` directory contains pure C code that is unrelated from either Mercurial or Python. The `mercurial/cyext` contains Cython extension code (although for linelog's case, the Cython extension is unrelated from Mercurial). Cython is now a hard dependence to simplify the code. Test Plan: `make local` and check `from mercurial.cyext import linelog` works.
