templater: drop extension point of engine classes (API)
I don't think this would ever be used by third-party extensions, as we've
heavily changed both the templater internals and the syntax since then.
The main reason of removing this API is that I want to move the parsing
function from the engine to the templater class so that we can peek keywords
and functions used in a user template. This change also removes reference
cycle between the templater and the engine.
Path conflict checking is currently disabled by default because of issue5716.
Turn it on for this test.
