Malcolm Tredinnick 29050ef999 Fixed #5420 -- Added support for delayed loading of model fields.
In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Malcolm Tredinnick 61a2708c41 Fixed #10356 -- Added pure-Python inheritance for models (a.k.a proxy models).
Large portions of this are needed for #5420, so I implemented it fully.
Thanks to Ryan Kelly for an initial patch to get this started.

Refs #5420.

Malcolm Tredinnick b4dd4d4bb7 Fixed #3163 -- Add a "Meta.managed" option to models.
This allows a model to be defined which is not subject to database table
creation and removal. Useful for models that sit over existing tables or
database views.

Thanks to Alexander Myodov, Wolfgang Kriesing and Ryan Kelly for the bulk of
this patch.

Malcolm Tredinnick f1f1d366c8 Removed django.db.models.options.Options.one_to_one_field.
The last use of it was removed in r9641 (it's internal API) and it's been
broken since r7477, as there's no longer a maximum of one OneToOneField per
model, so anything relying on it contained subtle bugs.

Malcolm Tredinnick d662ef5540 The first step in fixing a group of problems related to outputting a proper
"value" for a field that is a relation to another model.

This part adds the utility method on Model that should help in general.Also
cleans up the slightly ugly mess from r8957.

Malcolm Tredinnick fd0cc45828 [8721] introduced some internal field names. We hide them from the list of
valid field names in debugging output so that it doesn't confuse things.

Gary Wilson Jr c2ba59fc1d 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).

This is a backward incompatible change. The admin contrib app has been

Malcolm Tredinnick d800c0b031 Moved the settings of db_table to Options.contribute_to_class().
Some fields need to know the right db_table setting in their own
contribute_to_class(), so waiting until Options._prepare() is a little
inconvenient. This is a deep-internals change. No effect on external code.

Malcolm Tredinnick 0e692fda9c Fixed the way symmetrical many-to-many relations are recorded in the Options class.
These types of relations don't have reverse accessor names, so that name can be
used by a normal field on the model. Fixed #7107.

Russell Keith-Magee 12716794db Fixed #7350, #7202 -- Fixed serialization for multi-model inheritance, which had multiple problems:
* Serializers were including all superclass fields in their output. Now only local fields are included.
 * Implicit OneToOne primary keys were not correctly added to the metamodel, so they were always marked to be serialized, even though they were primary
 * Model saving was too aggressive about creating new parent class instances during deserialization. Raw save on a model now skips saving of the parent class.

Malcolm Tredinnick 3219a60167 Rewrote portions of the app- and model-cache initialisation to handle some corner cases. It is now possible to use m2m relations before everything is imported and still get the right results later when importing is complete. Also, get_apps() should always return the same results, so apps won't randomly disappear in the admin interface.
Also reorganised the structure of loading.py, since the number of global variables was exploding. The public API is still backwards compatible.

Fixed #1796 and #2438 (he claims, optimistically).
