24963	Missing `seekable()` method in Files	Carson Gee	nobody	"Neither in django/core/files/utils.py or django/core/files/base.py::File is the seekable method implemented.  In python 3 this results in issues when attempting to use python standard interfaces such as `bz2` or `tarfile` and results in `AttributeError: 'File' object has no attribute 'seekable'` errors when using File class objects.

I'm not sure the best way to patch this though.  The seekable property isn't available in python2, but I think it can be duplicated in 2, by checking if it has `seek`, `tell`, and `truncate` based on https://docs.python.org/3/library/io.html#io.IOBase.seekable.  I'm happy to write the patch, but it would be worth knowing the preference for how to fix it.
