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

Alternative approach to fix ticket 56.
Based on discussion #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.
Now with tests. Reworked (see #308).
