Shortly after `SimpleListFilter` landed in [16144], there were talks on
IRC with jezdez, carljm and apollo13 about allowing filter lookups to be
based on the available data. Taking the `DecadeBornListFilter ` example
from the doc
(http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter),
you might want to only display the lookups for the decades where people
were actually born in. This requires the `lookups()` method to have access
to the `ModelAdmin`'s queryset, somehow.
I'm attaching a patch with a suggested implementation.
