Full support 64 bit integers with BigInt

[renatoalencar]

Well this is not full ready yet, but I'd like to bring some discussions:

1. To use SQLite int64 instead of int32, because JS Number type is always 64 bits;
2. That would make possible to serialize BigInt in queries;
3. Also would make possible to use numbers (with BigInt) between 2^53 and -2^53.
