Fixed #17788 -- Added batch_size argument to qs.bulk_create()

Browse Source 
The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.

Thanks to everybody who participated in the discussions at Trac.

@@ -106,6 +106,11 @@ Django 1.5 also includes several smaller improvements worth noting:
* The :ref:`receiver <connecting-receiver-functions>` decorator is now able to
connect to more than one signal by supplying a list of signals.
* :meth:`QuerySet.bulk_create()
<django.db.models.query.QuerySet.bulk_create>` has now a batch_size
argument. By default the batch_size is unlimited except for SQLite where
single batch is limited so that 999 parameters per query isn't exceeded.
