index: verify we have enough space left when writing index entries In our code writing index entries, we carry around a `disk_size` representing how much memory we have in total and pass this value to `git_encode_varint` to do bounds checks. This does not make much sense, as at the time when passing on this variable it is already out of date. Fix this by subtracting used memory from `disk_size` as we go along. Furthermore, assert we've actually got enough space left to do the final path memcpy.
