Gary Pendergast 4dcb7a0fa9 Bootstrap: Use `dirname()` when loading `class-wp-hook.php` from `plugin.php`. 
To allow `plugin.php` to be loaded before the rest of WordPress is loaded, it cannot rely on WordPress constants, such as `ABSPATH` and `WPINC`.

Instead, we can assume that `class-wp-hook.php` will be in the same directory as `plugin.php`, so `dirname( __FILE__ )` will give us the correct path to load from.

Gary Pendergast 5a632be944 Hooks: Add the new class `WP_Hook`, and modify hook handling to make use of it. 
Filters and actions have been the basis of WordPress' plugin functionality since time immemorial, they've always been a reliable method for acting upon the current state of WordPress, and will continue to be so.

Over the years, however, edge cases have cropped up. Particularly when it comes to recursively executing hooks, or a hook adding and removing itself, the existing implementation struggled to keep up with more complex use cases.

And so, we introduce `WP_Hook`. By changing `$wp_filter` from an array of arrays, to an array of objects, we reduce the complexity of the hook handling code, as the processing code (see `::apply_filters()`) only needs to be aware of itself, rather than the state of all hooks. At the same time, we're able te handle more complex use cases, as the object can more easily keep track of its own state than an array ever could.

Aaron Jorbin a138374ec8 Bootstrap/Load: Include Plugin API via `require_once` 
Currently, auto-prepended files need to directly modify the globals in order to add filters and actions. This is a bad idea. Globals are bad. You should never directly interact with the Plugin globals.

Aaron Jorbin 7e14c27bb9 Bootstrap/Load: Revert Plugin Global restoration around `advance-cache.php`. 
First added in [37588] and later modified in [38224], the idea was to ensure that filters/actions added before `advance-cache.php` would not disappear if `advance-cache.php` overloaded the filters/actions with code such as `$wp_filter = array()`. This is an edge case and one that there is no documented case of existing.

This restores the behavior from WordPress 4.5 and before. It is strongly encouraged that developers using `advance-cache.php` to use the Plugins API that is available before the loading of `advance-cache.php` rather than directly interacting with any of the globals.

Gary Pendergast 4ac3feaa64 Boostrap/Load: Improve forward compatiblity of plugin global backup methods. 
[37588] added methods to backup the plugin globals, for ensuring that advanced cache drop-ins don't overwrite hooks that've been added earlier in the load process.

The method for restoring the plugin globals wasn't compatible with the implementation of `WP_Hook` in #17817. `WP_Hook` implements `ArrayAccess`, so `_restore_plugin_globals()` was treating it as an array, and inadvertantly overwriting the `WP_Hook` object with a plain array.

To avoid having to re-write this code as part of #17817, we now use `add_filter()` to restore any hooks that were added by cache drop-ins, which `WP_Hook` correctly supports.

Props pento, jorbin.
