  Issue 8143: sync unquote in urlparse with urllib; add comment about doing so.

  unquote is duplicated in the two files to avoid a circular reference.
  (This is fixed in Python3.)  Updates keep getting made to the public unquote
  without fixing the urlparse one, however, so this fix syncs the two
  and adds a comment to both to make sure changes are applied to both.
