 The `is_ssl()` function is currently in `functions.php` making it
 unavailable to `advanced-cache.php`.

 Batcache and other similar plugins end up copying `is_ssl()` verbatim for
 their own use.

 I think this is a safe move for a few reasons:
 * Other common `is_` functions are there
 * It's a highly useful utility function that developers should safely
 assume is always available inside of WordPress, no matter how early
 * Traditional plugins and themes cannot load early enough to need to
 manually include it
 * WordPress does not `require_once` the `functions.php` file, meaning
 anyone trying to pre-include it in their own `advanced-cache.php`
 implementation would encounter fatal errors

 Patch imminent.
