Over the course of the years, we developed a sub-command that gathers
diagnostic data into a .zip file that can then be attached to bug reports.
This sub-command turned out to be very useful in helping Scalar developers
identify and fix issues.

Changes since v1:

 * Instead of creating a throw-away repository, staging the contents of the
   .zip file and then using git write-tree and git archive to write the .zip
   file, the patch series now introduces a new option to git archive and
   uses write_archive() directly (avoiding any separate process).
 * Since the command avoids separate processes, it is now blazing fast on
   Windows, and I dropped the spinner() function because it's no longer
   needed.
 * While reworking the test case, I noticed that scalar [...] <enlistment>
   failed to verify that the specified directory exists, and would happily
   "traverse to its parent directory" on its quest to find a Scalar
   enlistment. That is of course incorrect, and has been fixed as a "while
   at it" sort of preparatory commit.
 * I had forgotten to sign off on all the commits, which has been fixed.
 * Instead of some "home-grown" readdir()-based function, the code now uses
   for_each_file_in_pack_dir() to look through the pack directories.
 * If any alternates are configured, their pack directories are now included
   in the output.
 * The commit message that might be interpreted to promise information about
   large loose files has been corrected to no longer promise that.
 * The test cases have been adjusted to test a little bit more (e.g.
   verifying that specific paths are mentioned in the output, instead of
   merely verifying that the output is non-empty).

  archive: optionally add "virtual" files
  scalar: validate the optional enlistment argument
  Implement `scalar diagnose`
  scalar diagnose: include disk space information

  scalar: teach `diagnose` to gather packfile info
  scalar: teach `diagnose` to gather loose objects information
