function hook_field_views_data_views_data_alter

Alter the views data on a per field basis.

Field module's Implements hook_views_data_alter() invokes this for each field in the module that defines the field type (as declared in the field array). It is not invoked in other modules.

Unlike hook_field_views_data_alter(), this operates on the whole of the views data. This allows a field module to add data that concerns its fields to other tables, which would not yet be defined at the point when hook_field_views_data() and hook_field_views_data_alter() are invoked. For example, entityreference adds reverse relationships on the tables for the entities which are referenced by entityreference fields.

(Note: this is weirdly named so as not to conflict with hook_field_views_data_alter().)
