s4:ldb Add ldb_ldif_write_string() and python wrappers
This allows us to turn a python LdbMessage back into a string.

commit 3ed33813bb6aa1ca932372c2a2ce36152b6af50b
Author: Andrew Bartlett <abartlet at samba.org>
Date: Wed Aug 26 15:01:12 2009 +1000
s4:ldb Add hooks to get/set the flags on a ldb_message_element
Also add tests to prove that we got this correct, and correct the
existing tests which used the wrong constants.
