Removed oldforms, validators, and related code: * Removed `Manipulator`, `AutomaticManipulator`, and related classes. * Removed oldforms specific bits from model fields: * Removed `validator_list` and `core` arguments from constructors. * Removed the methods: * `get_manipulator_field_names` * `get_manipulator_field_objs` * `get_manipulator_fields` * `get_manipulator_new_data` * `prepare_field_objs_and_params` * `get_follow` * Renamed `flatten_data` method to `value_to_string` for better alignment with its use by the serialization framework, which was the only remaining code using `flatten_data`. * Removed oldforms methods from `django.db.models.Options` class: `get_followed_related_objects`, `get_data_holders`, `get_follow`, and `has_field_type`. * Removed oldforms-admin specific options from `django.db.models.fields.related` classes: `num_in_admin`, `min_num_in_admin`, `max_num_in_admin`, `num_extra_on_change`, and `edit_inline`. * Serialization framework * `Serializer.get_string_value` now calls the model fields' renamed `value_to_string` methods. * Removed a special-casing of `models.DateTimeField` in `core.serializers.base.Serializer.get_string_value` that's handled by `django.db.models.fields.DateTimeField.value_to_string`. * Removed `django.core.validators`: * Moved `ValidationError` exception to `django.core.exceptions`. * For the couple places that were using validators, brought over the necessary code to maintain the same functionality. * Introduced a SlugField form field for validation and to compliment the SlugField model field (refs #8040). * Removed an oldforms-style model creation hack (refs #2160). git-svn-id: http://code.djangoproject.com/svn/django/trunk@8616 bcc190cf-cafb-0310-a4f2-bffc1f526a37
