3-way object merge API

Performs a git-style 3-way deep merge of two edits over a common base, auto-merging non-conflicting changes and listing conflicts where both sides changed a path differently. Answers 'How do I merge two concurrent edits to a config?', 'Where do ours/theirs conflict against the base?'.
