These filters will allow WordPress plugins to modify the cookies and
plugins lists used by WP Super Cache instead of the add/delete functions
introduced in #574 and #580.
Duplicate entries are removed so the filter function does not need to
worry about that. The filters fire on 'init'.

Example filter code:

function myplugin_add_wpsc_cookies( $cookies ) {
    $cookies[] = 'myplugin';
    return $cookies;
}
add_filter( 'wpsc_cookies', 'myplugin_add_wpsc_cookies' );
function myplugin_delete_wpsc_cookies( $cookies ) {
    if ( in_array( 'myplugin', $cookies ) ) {
        unset( $cookies[ array_search( 'myplugin', $cookies ) ] );
    }
    return $cookies;
}
add_filter( 'wpsc_cookies', 'myplugin_delete_wpsc_cookies' );

As suggested by @johnbillion and @andreasciamanna in #580.

You can also use do_action to add a cookie like this:

do_action( 'wpsc_add_cookie', 'euCookie' );

Use wpsc_delete_cookie to remove the cookie.

        unset( $cookies[ array_search( 'myplugin', $cookies ) ] );
    }
    return $cookies;

add_filter( 'wpsc_cookies', 'myplugin_delete_wpsc_cookies_filter' );`

As I've tried to explain here I think an action is more appropriate and safer than a filter.

If properly used, a hook to the filter could mess with the content of $cookies.

An action seems to me more straight-forward.

In a plugin, I could call do_action( 'wpsc_add_cookie', 'my-plugin-cookie-name' );

And in wp-super-cache, wpsc_add_cookie() could be hooked to that action:

function wpsc_add_cookie( $name ) {
	global $wpsc_cookies;
	if (
		! isset( $wpsc_cookies ) ||
		! is_array( $wpsc_cookies ) ||
		! in_array( $name, $wpsc_cookies )
	) {
		$wpsc_cookies[] = $name;
		wp_cache_setting( 'wpsc_cookies', $wpsc_cookies );
	}
}
add_action( 'wpsc_cookies' );

Ah. I wondered about that. Your example makes sense and avoids running an apply_filters() on every page load if there's no outside code that wants to modify the cookie list. Thanks. I'll modify the PR.

Instead of using filters to change cookie/plugin lists I've added four
actions:
wpsc_add_plugin
wpsc_delete_plugin
wpsc_add_cookie
wpsc_delete_cookie

For example, to add a cookie name called 'euCookie':

`do_action( 'wpsc_add_cookie', 'euCookie' );`

Props @andreasciamanna.

I updated the PR, changing the filters to actions so you can do do_action( 'wpsc_add_cookie', 'euCookie' ); to add a cookie called 'euCookie'.

Thanks a lot!

We are a bit at the end of our development cycle, but I'll see if I can manage to include it in the next WPML bugfix release.

If not, it will be included in the following one.

Just tested it with add_cookie_plugin_filters branch and it works perfectly.

Found a bug in wp-cache-phase2.php though: I'll create a PR.
