This is a performance optimization and also fixes test errors with the
upcoming merge of contrib tests into tests/. The tests failed on MySQL
because the models with GeometryField were being checked but the
non-GIS MySQL backend didn't know how to handle them.

During the autumn DST change, the template engine would fail to convert
the naive representation of now when USE_TZ = True. Passing now in UTC
eliminates the issue.

This reduces the length of rope RequestContext gives users to hang
themselves with.
Thanks Alex Hill for the report and Tim Graham for the review.

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.
