refactor how file changes and hashes are handled, and add tests for hashes
This involved a few different changes that all worked together:
* Making fileChanged public as ChangedFile, and reorganizing how it's
created/used a bit.
* Renaming the CommitInterface methods to be clearer, and passing in a
`[]ChangedFile` into `ExpectedHash` (previously just `Hash`) rather than
trees.
* Adding tests for the gen*Hash functions.
