repair: speed up stripping of many roots repair.strip() expects a set of root revisions to strip. It then builds the full set of descedants by walking the descandants of each. It is rare that more than a few roots get passed in, but if that happens, it will wastefully walk the changelog for each root. So let's just walk it once.

When there were tens of thousands of commits to strip, this resulted in quadratic behavior with that extension.

revset: drop TODO comment about sorting issue of fullreposet The bootstrapping issue was addressed at the parsing phase and we expect that fullreposet.__and__() fully complies to the smartset API, in which 'self & other' should return a result set in self's order. See also 90455e7bf543.
