This also fixes a test failure on Python 2 when Django is installed in a
non-ASCII path. This problem cannot happen on Python 3.

* Added helpers to test uncached and cached access.
* Fixed test_project_root_locale: it duplicated test_locale_paths_setting.
* Rewrote test_only_new_files: test more cases.

* When some old files contain errors, the second call to
  gen_filenames() should return them.
* When some new files contain errors, the first call to
  gen_filenames(only_new=True) should return them.

Thanks Flavio Curella and Berker Peksag for the initial patch.

Forwardport of ae1d663b
from stable/1.8.x plus more.

Implemented __str__() to return the string-representation of the
proxied object, not the proxy itself, if the lazy object didn't have
a string-like object in its resultclasses.

Renamed the mime_type properties of RssFeed and Atom1Feed to
content_type and start deprecation for the old names.

This is a security fix; disclosure to follow shortly.

Report and original patch by Kay Cha.

The function no longer flushes zfile after each write as doing so can
lead to the gzipped streamed content being larger than the original
content; each flush adds a 5/6 byte type 0 block. Removing this means
buf.read() may return nothing, so only yield if that has some data.
Testing shows without the flush() the buffer is being flushed every 17k
or so and compresses the same as if it had been done as a whole string.
