Utility method for getting a Site object

[James Bennett]

Fairly often, I find myself writing code which needs a Site and which, as a general best practice, falls back to RequestSite if contrib.sites isn't installed. Which means writing this code, or something like it, over and over:

from django.contrib.sites.models import RequestSite
from django.contrib.sites.models import Site

if Site._meta.installed:
    site = Site.objects.get_current()
else:
    site = RequestSite(some_request_object)

Given how common this idiom will be for code which wants to properly support the RequestSite fallback, it'd be nice to just have a utility method somewhere in contrib.sites which could just take an HttpRequest object and return either a Site or a RequestSite as appropriate.

Proposed utility method

[Gabriel Hurley]

Duplicate of #10235 (which adds a method to do exactly this as part of it's solution), #8960 (which needs this for the admin 'view on site' function), and #10608 (which would add this code to all the contrib apps). I'll bring this up on the Django Dev list to see if we can get a consensus on the solution for all three tickets.
