Synchronizes actions that are provided by modules in hook_action_info().

Actions provided by modules in hook_action_info() implementations are synchronized with actions that are stored in the actions database table. This is necessary so that actions that do not require configuration can receive action IDs.

Parameters

$delete_orphans: If TRUE, any actions that exist in the database but are no longer found in the code (for example, because the module that provides them has been disabled) will be deleted.
