In so doing, I realized that the use of git_buf in the hashsig API was not needed and actually just made it harder to use, so I tweaked that API as well. Note that the similarity metric is still not hooked up in the find_similarity code - this is just setting out the function that will be used.

Also, this implements a different approach to similarity measurement based on a Rabin-Karp rolling hash where we only keep the top 100 and bottom 100 hashes. In theory, that should be sufficient samples to given a fairly accurate measurement while limiting the amount of data we keep for file signatures no matter how large the file is.
