[issue27645] Supporting native backup facility of SQLite

[Serhiy Storchaka]

It seems to me that the code could be much simpler (and more bugfree) if support only a Connection instance as a target. It is easy to create a Connection instance in Python:

    with sqlite3.connect(filename) as dest:
        source.backup(dest)

But this would save around 50 lines of complex C code. And I'm not sure this code is correct.
