The main implementation of all the Form logic. Note that this class is
different than Form. See the comments by the Form class for more info. Any
improvements to the form API should be made to this class, not to the Form
class.

Rearrange the fields according to field_order.
field_order is a list of field names specifying the order. Append fields
not included in the list in the default order for backward compatibility
with subclasses not overriding field_order. If field_order is None,
keep all fields in the order defined in the class. Ignore unknown
fields in field_order to allow disabling fields in form subclasses
without redefining ordering.

Update the content of `self._errors`.
The `field` argument is the name of the field to which the errors
should be added. If it's None, treat the errors as NON_FIELD_ERRORS.
The `error` argument can be a single error, a list of errors, or a
dictionary that maps field names to lists of errors. An "error" can be
either a simple string or an instance of ValidationError with its
message attribute set and a "list or dictionary" can be an actual
`list` or `dict` or an instance of ValidationError with its
`error_list` or `error_dict` attribute set.
If `error` is a dictionary, the `field` argument *must* be None and
errors will be added to the fields that correspond to the keys of the
dictionary.

Hook for doing any extra form-wide cleaning after Field.clean() has been
called on every field. Any ValidationError raised by this method will
not be associated with a particular field; it will have a special-case
association with the field named '__all__'.
