Same name and namespace in other branches

1. 7 page_manager/page_manager.module \page_manager_compare_task_handlers()

Compare a single task handler from two lists and provide the correct one.

Task handlers can be gotten from multiple sources. As exportable objects, they can be provided by default hooks and the database. But also, because they are tightly bound to tasks, they can also be provided by default tasks. This function reconciles where to pick up a task handler between the exportables list and the defaults provided by the task itself.

Parameters

$result: A list of handlers provided by export.inc

$handlers: A list of handlers provided by the default task.

$name: Which handler to compare.

Return value

Which handler to use, if any. May be NULL.
