  Create git_diff_line and extend git_diff_hunk
  
  Instead of having functions with so very many parameters to pass
  hunk and line data, this takes the existing git_diff_hunk struct
  and extends it with more hunk data, plus adds a git_diff_line.
  Those structs are used to pass back hunk and line data instead of
  the old APIs that took tons of parameters.
  
  Some work that was previously only being done for git_diff_patch
  creation (scanning the diff content for exact line counts) is now
  done for all callbacks, but the performance difference should not
  be noticable.
