Summary:
I didn't notice the test failure because clang-format was not installed.
Might be a good idea to make it a hard error.
Test Plan: Run test-check-clang-format.t

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.
