Add a new BinaryDeltaInputStream that applies a delta provided by
another InputStream to a given base. Because delta application needs
random access to the base, the base itself cannot be yet another
InputStream. But at least this enables streaming of the result.
Add a simple test using delta hunks generated by C git.
