function _field_read_fields_cache

Helper function used by _field_info_collate_fields().

This function keeps a static variable of all raw field configurations, without any defaults loaded or "enriched" with cross-references between its instances and the storage system.

This cache exists so that when instances are read in field_read_instances(), they have a fully loaded list of all fields in the system that they can reference to determine default values and if the field has been disabled.
