Title: MySQL bigint primary keys

`mysql_insert_id()` returns an unsigned 64-bit integer, but `INT2NUM()` does not handle these correctly.

I added tests in a second commit because I wasn't sure of their quality or how they should fit into the suite. Should all drivers support SQL:2003 bigint?

`affected_rows` on the same line needs this same treatment, but is beyond the scope of this PR.
