Context is already provided: the wp_query object itself. This was only
introduced in WP 2.9 so most plugins still have to catch up.

get_posts() also sets 'caller_get_posts' => true, so plugins can use that.
In WP 3.1 'caller_get_posts' was then renamed to 'ignore_stickies':

We should probably un-deprecate 'caller_get_posts'.
