largefiles: replace manifestdict.__contains__, don't extend class We're soon going to add an alternative manifest class (treemanifest). Rather than extending both those classes by largesfiles versions, let's replace the method on the manifest instances.

files: split reusable implementation into cmdutil for subrepo support

files: use ctx object to access dirstate This allows the cmdutil method to not need to be passed the repo as well as the ctx.

copies: added manifests to computenonoverlap Commit 30219bd46ed7 changed the computenonoverlap api's to not require the manifests. We actually need the manifests in the remotefilelog extension so we can find the file nodes for the various files that change. Let's add it back to the function signature with a note explaining why. This doesn't affect any behavior.
