Fix parent rewriting in --early-output
We cannot tell a node that has been checked and found not to be interesting (which does not have the TREECHANGE flag) from a node that hasn't been checked if it is interesting or not, without relying on something else, such as object->parsed. But an object can get the "parsed" flag for other reasons. Which means that "TREECHANGE" has the wrong polarity. This changes the way how the path pruning logic marks an uninteresting commits. From now on, we consider a commit interesting by default, and explicitly mark the ones we decided to prune. The flag is renamed to "TREESAME". Then, this fixes the logic to show the early output with incomplete pruning. It basically says "a commit that has TREESAME set is kind-of-UNINTERESTING", but obviously in a different way than an outright UNINTERESTING commit. Until we parse and examine enough parents to determine if a commit becomes surely "kind-of-UNINTERESTING", we avoid rewriting the ancestry so that later rounds can fix things up.
