This significantly improves performance on PyPy. The previous
implementation would generate a new class on every single request,
which is relatively slow.

This dramatically improves performance on PyPy. The following benchmark:
python -mtimeit -s "from django.utils.functional import allow_lazy; from django.utils.translation import ugettext_lazy; f = allow_lazy(lambda s: s, str)" "f(ugettext_lazy('abc'))"
goes from 390us per loop to 165us.

This script uses the unmaintained hotshot module (gone on Python 3)
and doesn't seem to be Django specific in any way.

Since 1.7 models need to declare an explicit app_label if they are not
in an application in INSTALLED_APPS or were imported before their
application was loaded.

If importing or initializing a template backend fails, attempting to
access this template backend again must raise the same exception.

In addition to ImproperlyConfigured, Engine.get_default() may also raise
ImportError or other exceptions. It's better to catch all exceptions in
places where the default engine isn't strictly required.

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.

A change in Python test discovery [1] causes the old packages that raised
an error to be discovered; now we use a common directory that's
ignored during discovery. Refs #23763.

make_bytes() assumed that if the Content-Encoding header is set, then
everything had already been dealt with bytes-wise, but in a streaming
situation this was not necessarily the case.
make_bytes() is only called when necessary when working with a
StreamingHttpResponse iterable, but by that point the middleware has
added the Content-Encoding header and thus make_bytes() tried to call
bytes(value) (and dies). If it had been a normal HttpResponse,
make_bytes() would have been called when the content was set, well
before the middleware set the Content-Encoding header.
This commit removes the special casing when Content-Encoding is set,
allowing unicode strings to be encoded during the iteration before they
are e.g. gzipped. This behaviour was added a long time ago for #4969 and
it doesn't appear to be necessary any more, as everything is correctly
made into bytes at the appropriate places.
Two new tests, to show that supplying non-ASCII characters to a
StreamingHttpResponse works fine normally, and when passed through the
GZip middleware (the latter dies without the change to make_bytes()).
Removes the test with a nonsense Content-Encoding and Unicode input - if
this were to happen, it can still be encoded as bytes fine.

The method is mainly intended for use with UUIDField. For UUIDField we
want to call the field's default even when primary key value is
explicitly set to None to match the behavior of AutoField.
Thanks to Marc Tamlyn and Tim Graham for review.

Specifically in rendering shortcuts, template responses, and class-based
views that return template responses.
Also added a test for render_to_response(status=...) which was missing
from fdbfc980.
Thanks Tim and Carl for the review.
