[PATCHES] Port ldb to Python 3

Hi Petr,

I've reviewed most of the patches see
https://git.samba.org/?p=metze/samba/wip.git;a=shortlog;h=refs/heads/master3-python

I have just a couple of questions.

This one needs to be squashed
https://git.samba.org/?p=metze/samba/wip.git;a=commitdiff;h=985f384e1fe3d998c032eb17f01d991ea33fdbfb
into
https://git.samba.org/?p=metze/samba/wip.git;a=commitdiff;h=b8aaa4a020d6d36972fdf6fb33d762b9321699a7
otherwise the build with --picky-developer fails.

I've added some TODO's here:
https://git.samba.org/?p=metze/samba/wip.git;a=commitdiff;h=5e00a20e55baa3f83d69bf0dc9280527a3af7ae1

As I'm trying to use --extra-python=/usr/bin/python3 on ubuntu 14.04

I've got the following when trying to bump the ldb version.

https://git.samba.org/?p=metze/samba/wip.git;a=commitdiff;h=0604992f1a185557102881e4837bef291696053e

A pyldb-util.cpython-34m-1.1.22.sigs is generated, the question would
how can we have just
one pyldb-util-1.1.22.sigs that is checked for both versions or we need
a python2 and a python3 file. But that should not depend an the exact
python3 version.
