Add access modifiers to `WP_Text_Diff_Renderer_Table` that are compatible with its parent class. Some of the inline docs suggest access that, if implemented, would produce fatal errors.

Add magic methods for BC: __get(), __set(), __isset(), __unset(), and __call().

See #27881, #22234.

In `wpdb`, make some things explicitly `public`. Do not set anything to `private`. This would instantly blow up `hyperdb` in the wild.

In `WP_Filesystem_Base`, the constructor is a noop, so it shouldn't even be declared. Setting it implies that `parent::__construct()` should be called by its subclasses.

Upgrade `_WP_List_Table_Compat` to PHP5-style constructor.

Add `public` to methods/members of `WP_Role`.
Add `public` to methods/members of `WP_User` where appropriate. Don't set `private` where indicated until more study has occurred and tests have been written for compatibiliy with existing magic methods.

`WP_Query` was only missing one access modifier.

Add access modifier (`public`) to applicable class methods/members of `WP_Rewrite`. I am not brave enough to set some of the `var`s to `private` without more testing.
