We assumed that any OneToOneField's in a child model must be the
parent link and raised an error when parent_link=True was not
specified. This patch allows to specify multiple OneToOneField's to
the parent model.
OneToOneField's without a custom related_name will raise fields.E304
and fields.E305 so this should warn users when they try to override
the auto-created OneToOneField.
The subtract_temporals() database operation was not handling expressions
returning SQL params in mixed database types.

Thanks Reupen Shah for the report.
Model.save_base() is called directly when loading fixtures and assumes
existing rows will be updated. Branching of "raw" allows to maintain
the optimization introduced in #29260 while supporting this edge case.

Thanks Reupen Shah for the report.
This allows adding foreign key constraints inline and changing data in
the same migration on PostgreSQL 10+.
Regression in 738faf9da2.
Thanks Janne Rönkkö for the report and Simon Charette for the
implementation idea and review.
Clearing the SELECT clause in Query.has_results was orphaning GROUP BY
references to it.
Thanks Thierry Bastian for the report and Baptiste Mispelon for the
bisect.

Unnecessary since cef3f2d3c6. When
USE_TZ=True, conn_tznames is always passed to methods that use
typecast_timestamp(). Therefore, it can return naive datetimes.
inspect.getcallargs() was deprecated in Python 3.5 and the Signature
API (PEP 362) has better support for decorated functions (by default,
it follows the __wrapped__ attribute set by functools.wraps for
example).
There was a special case in this property to return None when the
database backend supports time zone. However, only the PostgreSQL
backend supports time zones and it never uses this property.
This was an issue anymore on backends that allows conflicts to be
ignored (Refs #19544) as long the provided values were coercible to the
expected type. However on the remaining backends that don't support
this feature, namely Oracle, this could still result in an
IntegrityError.
By attempting to coerce the provided values to the expected types in
Python beforehand we allow the existing value set intersection in
ManyRelatedManager._get_missing_target_ids to prevent the problematic
insertion attempts.
Thanks Baptiste Mispelon for triaging this old ticket against the
current state of the master branch.
This prevent having to pass simple_col through multiple function calls
by defining whether or not references should be resolved with aliases
at the Query level.
