We're a bit lax with the command-line parsing, as the command is intended to be called only by one internal user: the add--interactive script. Implement add --interactive's status command in add-interactive.c and use it in builtin add--helper.c. It prints a numstat comparing changed files between a) the worktree and the index; b) the index and the HEAD. To do so, we use run_diff_index() and run_diff_files() to get changed files, use the diffstat API on them to get the numstat and use a combination of a hashmap and qsort() to print the result in O(n) + O(n lg n) complexity. This is the first interactive add command implemented in C of those anticipated by the previous commit, which introduced the add--helper built-in.
