Both backends order NULLs first on ascending ordering and last on
descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when
asc(nulls_first) and desc(nulls_last) are used since it prevents indice
usage.

deserialize_db_from_string() loads the full serialized database
contents, which might contain forward references and cycles. That
caused IntegrityError because constraints were checked immediately.
Now, it loads data in a transaction with constraint checks deferred
until the end of the transaction.

Fixed #29979 , Refs #17337 -- Extracted AutoField field logic into a mixin and refactored AutoFields.
...
This reduces duplication by allowing AutoField, BigAutoField and
SmallAutoField to inherit from IntegerField, BigIntegerField and
SmallIntegerField respectively. Doing so also allows for enabling the
max_length warning check and minimum/maximum value validation for auto
fields, as well as providing a mixin that can be used for other possible
future auto field types such as a theoretical UUIDAutoField.

Refs #25367 -- Moved Oracle Exists() handling to contextual methods.

Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the following cases.
1. When part of a SELECT clause.
2. When part of a ORDER BY clause.
3. When compared against another expression in the WHERE clause.
This commit moves the systematic CASE WHEN wrapping of Exists.as_oracle
to contextual .select_format, Lookup.as_oracle, and OrderBy.as_oracle
methods in order to avoid unnecessary wrapping.

Used time.monotonic() instead of time.time() where applicable.
...
time.monotonic() available from Python 3.3:
- Nicely communicates a narrow intent of "get a local system monotonic
clock time" instead of possible "get a not necessarily accurate Unix
time stamp because it needs to be communicated to outside of this
process/machine" when time.time() is used.
- Its result isn't affected by the system clock updates.
There are two classes of time.time() uses changed to time.monotonic()
by this change:
- measuring time taken to run some code.
- setting and checking a "close_at" threshold for for persistent db
connections (django/db/backends/base/base.py).
