Created a class in util called chunkbuffer that buffers reads from an
iterator over strings (aka chunks).
Also added to util (for future use) is a generator function that
iterates over a file n bytes at a time.
Lastly, localrepo was changed to use this new chunkbuffer class when
reading changegroups form the local repository.
