/**
* Store and retrieve keyed data for later verification by unit tests.
*
* This function is a simple in-memory key-value store with the
* distinction that it stores all values for a given key instead of
* just the most recently set value. field_test module hooks call
* this function to record their arguments, keyed by hook name. The
* unit tests later call this function to verify that the correct
* hooks were called and were passed the correct arguments.
*
* This function ignores all calls until the first time it is called
* with $key of NULL. Each time it is called with $key of NULL, it
* erases all previously stored data from its internal cache, but also
* returns the previously stored data to the caller. A typical usage
* scenario is:
*
* @code
* // calls to field_test_memorize() here are ignored
*
* // turn on memorization
* field_test_memorize();
*
* // call some Field API functions that invoke field_test hooks
* FieldStorageConfig::create($field_definition)->save();
*
* // retrieve and reset the memorized hook call data
* $mem = field_test_memorize();
*
* // make sure hook_field_storage_config_create() is invoked correctly
* assertEqual(count($mem['field_test_field_storage_config_create']), 1);
* assertEqual($mem['field_test_field_storage_config_create'][0], array($field));
* @endcode
*
* @param $key
* The key under which to store to $value, or NULL as described above.
* @param $value
* A value to store for $key.
* @return
* An array mapping each $key to an array of each $value passed in
* for that key.
