function _book_access_options_restrict in Book access 6

Restricts the options available to who moves book pages between books.

We don't want users to be able to add child pages to pages they do not have update grants for; therefore, we remove select options which point to book pages user does not have that grant.

Parameters

$options: The options array used from book_outline_form() and the book edit form for the list of books to which the page can be moved to.
