/**
* Returns a cached mapping of protected and delete confirmation form ids.
*
* @param $reset
* (optional) Boolean whether to reset the static cache, flush the database
* cache, and return nothing (TRUE). Defaults to FALSE.
*
* @return
* An associative array containing:
* - protected: An associative array whose keys are protected form IDs and
* whose values are the corresponding module names the form belongs to.
* - delete: An associative array whose keys are 'delete form' ids and whose
* values are protected form ids; e.g.
* @code
* array(
* 'node_delete_confirm' => 'article_node_form',
* )
* @endcode
* A single delete confirmation form id can map to multiple registered
* $form_ids, but only the first is taken into account. As in above example,
* we assume that all 'TYPE_node_form' definitions belong to the same entity
* and therefore have an identical 'post_id' mapping.
