Marc Tamlyn 962bb9b6bd Refs #2443 -- Move the durationfield converter logic.
This reduces how frequently this logic is run significantly.

Thanks to Anssi for the suggestion.

Marc Tamlyn 5ca82e710e Fixed #24033 -- Use interval type on Oracle.
Use INTERVAL DAY(9) TO SECOND(6) for Durationfield on Oracle rather than
storing as a NUMBER(19) of microseconds.

There are issues with cx_Oracle which require some extra data
manipulation in the database backend when constructing queries, but it
handles the conversion back to timedelta objects cleanly.

Thanks to Shai for the review.

Marc Tamlyn 57554442fe Fixed #2443 -- Added DurationField.
A field for storing periods of time - modeled in Python by timedelta. It
is stored in the native interval data type on PostgreSQL and as a bigint
of microseconds on other backends.

Also includes significant changes to the internals of time related maths
in expressions, including the removal of DateModifierNode.

Thanks to Tim and Josh in particular for reviews.

Marc Tamlyn e9103402c0 Fixed #18757, #14462, #21565 -- Reworked database-python type conversions
Complete rework of translating data values from database

Deprecation of SubfieldBase, removal of resolve_columns and
convert_values in favour of a more general converter based approach and
public API Field.from_db_value(). Now works seamlessly with aggregation,
.values() and raw queries.

Thanks to akaariai in particular for extensive advice and inspiration,
also to shaib, manfre and timograham for their reviews.

Claude Paroz 6295ea0027 Replaced HAS_SPATIAL_DB by testing database feature

Aymeric Augustin 40bfd8561d Fixed #20420 -- Normalized query counts on Oracle.
This is achieved by inserting a fake entry in connection.queries when
not releasing a savepoint (since Oracle doesn't support that operation.)

Also removed the can_release_savepoints feature that was recently added,
but is superseded by this solution.

Aymeric Augustin a03d38ddd4 Added a flag for the ability to introspect nullable fields.
Previously this was conflated with another Oracle-specific behavior.

Tim Martin 27aa85246a Fixed #20897 -- Added make_cursor() for consistent cursor creation
In django.db.backends.BaseDatabaseWrapper, pulled the creation of
cursors in the non-debug case into a separate method, in order to
make behavior more consistent when overriding the cursor creation
in derived classes.

Aymeric Augustin cff59bedc2 Split ignores_nulls_in_unique_constraints feature.
Oracle and SQL Server don't have exactly the same limitations. It's
worth treating them differently.

Aymeric Augustin 8b5b199e20 Fixed #3214 -- Stopped parsing SQL with regex.
Avoided introducing a new regex-based SQL splitter in the migrations
framework, before we're bound by backwards compatibility.

Adapted this change to the legacy "initial SQL data" feature, even
though it's already deprecated, in order to facilitate the transition
to migrations.

sqlparse becomes mandatory for RunSQL on some databases (all but
PostgreSQL). There's no API to provide a single statement and tell
Django not to attempt splitting. Since we have a more robust splitting
implementation, that seems like a good tradeoff. It's easier to add a
new keyword argument later if necessary than to remove one.

Many people contributed to both tickets, thank you all, and especially
Claude for the review.
