Florian Apolloner bc7dd8490b Fixed #21171 -- Avoided starting a transaction when a single (or atomic queries) are executed.
Checked the following locations:

 * Model.save(): If there are parents involved, take the safe way and use
   transactions since this should be an all or nothing operation.

   If the model has no parents:

    * Signals are executed before and after the previous existing
      transaction -- they were never been part of the transaction.

    * if `force_insert` is set then only one query is executed -> atomic
      by definition and no transaction needed.

    * same applies to `force_update`.

    * If a primary key is set and no `force_*` is set Django will try an
      UPDATE and if that returns zero rows it tries an INSERT. The first
      case is completly save (single query). In the second case a
      transaction should not produce different results since the update
      query is basically a no-op then (might miss something though).

 * QuerySet.update(): no signals issued, single query -> no transaction
   needed.

 * Model/Collector.delete(): This one is fun due to the fact that is
   does many things at once.

   Most importantly though: It does send signals as part of the
   transaction, so for maximum backwards compatibility we need to be
   conservative.

   To ensure maximum compatibility the transaction here is removed only
   if the following holds true:

     * A single instance is being deleted.
     * There are no signal handlers attached to that instance.
     * There are no deletions/updates to cascade.
     * There are no parents which also need deletion.

Introspected database constraints instead of relying on _meta.related_objects
to determine whether or not a table or a column is referenced on rename
operations.

This has the side effect of ignoring both db_constraint=False and virtual
fields such as GenericRelation which aren't backend by database level
constraints and thus shouldn't prevent the rename operations from being
performed in a transaction.

Simon Charette 813805833a Fixed #27631 -- Prevented execution of transactional DDL statements when unsupported.
Executing a DDL statement during a transaction on backends that don't support
it silently commits, leaving atomic() in an incoherent state.

While schema_editor.execute() could technically be used to execute DML
statements such usage should be uncommon as these are usually performed through
the ORM. In other cases schema_editor.connection.execute() can be used to
circumvent this check.

Thanks Adam and Tim for the review.
