narrow: remove narrowrevlog Core now automatically enables ellipsis support on revlogs when repositories have narrow enabled. So, we no longer need to globally register the revlog flag as part of activating the narrow extension and this code can be deleted. A side effect of this change is that repositories will now raise an error on encountering an ellipsis flag when the narrow extension is loaded. Previously, loading the narrow extension on a non-narrow repo could result in silent usage of the ellipsis flag. This could lead to undetected bugs. I think the new behavior is more correct.

 came up the import to hgext, but nobody's got concrete improvement
 ideas as of then.
 
-Fold most (or preferably all) of narrowrevlog.py into core.

+Address commentary in manifest.excludedmanifestrevlog.add -
 specifically we should improve the collaboration with core so that
 add() never gets called on an excluded directory and we can improve
 the stand-in to raise a ProgrammingError.
 
-Figure out how to correctly produce narrowmanifestrevlog and
-narrowfilelog instances instead of monkeypatching regular revlogs at
-runtime to our subclass. Even better, merge the narrowing logic
-directly into core.
-
 Reason more completely about rename-filtering logic in
 narrowfilelog. There could be some surprises lurking there.
