function _field_info_collate_fields in Drupal 7

Collates all information on existing fields and instances.

Deprecated. This function is kept to ensure backwards compatibility, but has a serious performance impact, and should be absolutely avoided. See http://drupal.org/node/1915646.

Use the regular field_info_*() API functions to access the information, or field_info_cache_clear() to clear the cached data.
