Fix rename detection to use actual blob size The size data in the index may not reflect the actual size of the blob data from the ODB when content filtering comes into play. This commit fixes rename detection to use the actual blob size when calculating data signatures instead of the value from the index. Because of a misunderstanding on my part, I first converted the git_index_add_bypath API to use the post-filtered blob data size in creating the index entry. I backed that change out, but I kept the overall refactoring of that routine and the new internal git_blob__create_from_paths API because it eliminates an extra stat() call from the code that adds a file to the index. The existing tests actually cover this code path, at least when running on Windows, so at this point I'm not adding new tests to cover the changes.
