blame: use size_t for line counts in git_blame_hunk It is not unreasonable to have versioned files with a line count exceeding 2^16. Upon blaming such files we fail to correctly keep track of the lines as `git_blame_hunk` stores them in `uint16_t` fields. Fix this by converting the line fields of `git_blame_hunk` to `size_t`. Add test to verify behavior.
