The top-level listing was just getting a bit too long for my taste. So put all of the code in one directory and shrink the large top-level mess to a small top-level mess. NOTE: This commit only contains renames. The subsequent commit will actually make ripgrep build again. We do it this way with the naive hope that this will make it easier for git history to track the renames. Sigh.
