Move `Walker_Category` and `Walker_CategoryDropdown` into their own files via `svn cp`. Remove them from `category-template.php`. Load them in `category.php`. `svn cp` `category.php` over to `category-functions.php`, which also loads now in `category.php`.
See #33413. Built from https://develop.svn.wordpress.org/trunk@34110 git-svn-id: http://core.svn.wordpress.org/trunk@34078 1a063a9b-81f0-0310-95a4-ce76da25c4cd
