 Right now the checkbox in the posts list table only shows if the user can
 edit the post. I am working on a plugin that allows posts to be archived,
 which means they are not visible publicly, and are no longer editable
 (until unarchived).

 To do this, I have used the `map_meta_cap` filter to disallow the
 `edit_post` capability if the current `post_status` is `archive`. This is
 great because the post in the table no longer has a link to edit or quick
 edit, and if you use a direct URL to edit the post a message shows to user
 saying they are not allowed (having a custom message here that says the
 post is archived would be good, maybe there is already an easy way to do
 so?).

 The problem though, is that the checkbox also is gone in the list table.
 This does not allow a user to select archived posts and then use the
 "Unarchive" bulk action.

 Currently to get around this, I am looping over `debug_backtrace()` to
 check if the `current_user_can('edit_post', $id)` call is coming from the
 `column_cb` function or not and returning the appropriate value. Obviously
 this is not preferred though.

 There may be a better way than simply allowing a filter for the
 `column_cb` as well, but hopefully this explains the end goal.
