 Many plugins need to be able to deny the creation of new items,
 particularly for CPT use cases. Unfortunately this is not easy to do.

 I am suggesting a new cap for adding posts. Obviously, this has the
 potential to break quite a number of custom roles, but I think we can
 avoid that.

 Instead, it would by default simply map to edit_posts. It wouldn't
 actually get assigned to any roles, so it's more or less a meta cap.
 (Only, without an $id, because it'd be a new post even pre-auto-draft in
 some cases.) But it then opens up the ability for this to be filtered by a
 plugin.

 We could also potentially add this to the CPT capabilities array, but with
 the default being 'add_posts' => 'edit_posts'. Ultimately there are a few
 ways to implement this.

 Ideally, the cap should be used for the admin menu, for post-new.php, for
 the 'Add New' button (no more clunky hiding it via CSS), XML-RPC, and the
 post handler for post-new.
