Title: Bigint AutoField (fixes #56, #13774)

Alternative approach to fix ticket 56.
Based on discussion https://github.com/django/django/pull/49
This approach doesn't change AutoField behavior. Only those who need extended int range may use it.
It keeps values ranges consistent between databases. Also it works nice with related fields.
