narrow: move manifestlog overrides to core

With this and the previous patch, I couldn't measure any significant
difference from `hg files -r .` in a FireFox repo with 65k files. I
tried with both a flat-manifest and a tree-manifest version of
it. Neither had the narrow extension enabled.

# extension to emulate invoking 'patch.internalpatch()' at the time
# specified by '[fakepatchtime] fakenow'
