Iterating over File broken in Python 3

[Peter De Wachter]

django.core.files.File has an iterator to allow line-by-line access to the file. This does not work in Python 3 due to string/bytestring confusion. Attached patch fixes this and adds a regression test.

Fixed #22107 -- Fixed django.core.files.File object iteration.

Due to a mixup between text and bytes, iteration over
a File instance was broken under Python 3.

Thanks to trac user pdewacht for the report and patch.

I think this would be a good candidate for backporting...

The problem has probably been here since 1.5 but I only backported to 1.6 because it's the first release that has full Python 3 support (1.5 had "experimental" support if I remember correctly).
