Niels Lohmann b41e43fffc Bound diff()'s descent with a depth count instead of scanning the source ...

Now that operator== no longer recurses (#5390), diff() can keep its per-level
equality shortcut all the way down. It diffs recursively for the first
detail::recursion_depth_limit() levels, as merge_patch() does, and hands
anything deeper to diff_iteratively(). The nesting_exceeds() scan, which
cost about 30% on equal documents, is gone, and diff() is on par with
develop again.
