post_parent should accept an array of IDs

[scribu]

Currently, it's not possible to get a list of posts that have one of several parents, since the 'post_parent' query var only accepts an integer.

And, since a post can only have a single parent, there's only one possible interpretation for this:

get_posts( array( 'post_parent' => array( 1, 2, 3 ) ) );
