Thanks mehta.apurva at gmail.com for the report and the initial patch
and neaf for the complete patch.

Connection.features does not need to be confirmed any more, after
commit aa423575, rendering obsolete the workaround when using
TEST_MIRROR (Refs #16885, #17760).

This does remove the requirement to call features.confirm() method
before checking the properties.
Thanks cdestiger and Ramiro Morales for their work on the patch.

Generic views assumed any object's _meta will be model Options. This
is not true for ModelForms for example. Took isinstance(obj, Model)
in use instead.

Added kwargs for_concrete_model and for_concrete_models to ContentType
methods get_for_model() and get_for_models(). By setting the flag to
False, it is possible to get the contenttype for proxy models.

The reason for this was that git show included the whole changeset in
the output, but only the UTC timestamp was needed. By using git log
it is possible to get just the timestamp. The whole changeset can be
large, and can cause unicode encoding errors.

One is for the community, the other for the core team.

Thanks Reinout van Rees for the report.

This avoids adding each contributor as a remote.
