proposal: Go2: database/sql LastInsertId() and RowsAffected() uint64

[pjebs]

For Go2,

LastInsertId() and RowsAffected() should return uint64 instead of int64.

I came across an issue relating to this on MySQL recently.

[pjebs]

Another solution is LastInsertId() returns a string.

It is foreseeable that some databases have a primary key as a string (MySQL supports this) with no integer auto_increment.

In that case, a hypothetical driver should be able to return a string or interface{}.
