merge: return a mergeresult obj from manifestmerge(), calculateupdates() (API)
Earlier, manifestmerge() and calculateupdates() returns a tuple of three things.
I wanted to add one more thing to return value.
Introducing a special class which represents results of a merge will help
understand better and also ease adding new return values.
