[PATCH 0/3] Teach git diff-tree --stdin to diff trees

Here's two patches that implements diffing of trees: first a refactoring, then the actual functionality.

I'm not familiar with git's API, so I might have made mistakes in choosing or using functions. Extra eyeballs appreciated. But the test suite passes, it does what I want, and it does make StGit faster, so _I'm_ happy ...
