* `wp_ajax_get_comments()` relies on the `$post_id` global - even though `$_POST['p']` is passed to every action in the test methods. If `$post_id` is still lingering in between tests and doesn't match `p` in the request, the cap check might pass while the queries for comments will blow up. I added `unset( $GLOBALS['post_id'] )` to `Tests_Ajax_GetComments::setUp()`.
* If the global `$post_id` is empty, but `$_REQUEST['p']` is not, `$post_id` is now set to `absint( $_REQUEST['p'] )` and sanity-checked in `wp_ajax_get_comments()`.
* `map_meta_cap()` always assumes that `get_comment()` succeeds when checking for the `edit_comment` cap. It doesn't. I added sanity checks in a few places where it will break early if `get_post()` or `get_comment()` are empty.
* `wp_update_comment()` always assumes `get_comment()` succeeds. It doesn't. I added a check for empty.
All AJAX unit tests run and pass in debug mode. All general unit tests pass against these changes.

This provides nearly the same benefits without possibly receiving a stale object from get_userdata(),
which could affect authentication, and introduce side effects for plugins.

Enforce this by denying the 'manage_links' capability, which hides the All Links, Add New Link, and Link Categories screens. Hide WP_Widget_Links and the UI for the default_link_category as well.
Convert all references to 'posts and links' when handling reassignment on user deletion to just 'posts'.
see #21307.

wp-includes/admin-bar.php:
* Replace get_admin_url() and get_home_url() with admin_url() and home_url() and place them inside a switch/restore. Likewise replace current_user_can_for_blog() with current_user_can(). This avoids doing multiple switch restores.
wp-includes/ms-blogs.php:
* Deprecate the $validate argument to switch_to_blog(). This avoids a not very necessary call to get_blog_details(), possibly saving a few queries.
* Use $_wp_switched and $_wp_switched_stack instead of $switched and $switched_stack to make it less likely these globals will be stomped.
* Use GLOBALS to access blog_id and other globals. I've preferred this style lately since it makes it obvious a global is being used and avoids global blog_id being stomped by a local variable.
* Lose some is_object() checks. wp_get_current_user() always returns an object, for example.
* Call the new WP_Roles::reinit() method.
wp-includes/class-wp-xmlrpc-server.php:
* Replace current_user_can_for_blog() with current_user_can() and move it inside the switch/restore pair. This eliminates a switch/restore.
wp-includes/capabilities.php:
* Use array_keys() instead of $role => $data since $data is unused. I *think* this is a bit faster.
* Introduce WP_Roles::reinit(). This reinitializes WP_Roles and is used after switch_to_blog() has already update the blog ID in the wpdb object. If a global roles array is being used instead of the db, reinit is skipped.
* current_user_can_for_blog() now does a switch/restore. It didn't before meaning it could be reinitializing the user with the wrong role information for the current blog.
wp-includes/ms-settings.php:
* Define $_wp_switched_stack and $_wp_switched. This way switch_to_blog() and restore_current_blog() can rely on it being set.
wp-settings.php:
* Instantiate the WP_Roles global. This was it is always defined during init. To remove the WP_Roles checks from WP_Role and WP_User this would probably have to move before plugins are loaded, which might not be a good thing.
wp-includes/functions.php:
* Update wp_upload_dir() to reference _wp_switched.

Remove bogus checks for enabling/disabling the 'themes' menu (something core does not handle out of the box) when in the network admin.
