The `if (!pyldb_Dn_Check(pydn2))` might seem redundant, but we
need it to return Py_NotImplemented before the _OR_RAISE macro
raises TypeError.

087d43ac61 pyldb: adapt some simple dn methods to use LDB_DN_OR_RAISE()
We treat self as PyObject, and only trust its DN once it has been
laundered by PyErr_LDB_DN_OR_RAISE().

There are more of these to come in the next few commits, but these are
the simplest ones (on a textual level -- the others are simple too, but
look different).

This changes what happens all over the place
(lib/ldb/pyldb.c, source4/dns_server/pydns.c, source4/dsdb/pydsdb.c),
but causes no problems because it just checks what we always assumed.

fdc3212275 pyldb: Add ldb.disconnect() method to ensure DB handles are closed
This is vital in our backup code, which needs to actually close the
LMDB at the correct point.

The Python ldb object itself is left in more or less the same state as
one that has not connected to a server or database (it is a very
simple wrapper in itself), and can be reconnected using the .connect()
method.
