ldb: Mark _DEPRECATED_ ldb_msg_diff() and ldb_msg_canonicalize() functions
They are not quite safe to use (requires caller to steal
resulting message in own context) and may lead to holding
memory for too long.

s4-ldb: Implement ldb_msg_difference() function to accept a memory context
from client
Old implementation from ldb_msg_diff() was moved into
this this function but with changed interface
so that a memory context may be passed.
ldb_msg_diff() function is now based on ldb_msg_difference(),
which fixes a hidden leak - internal ldb_msg object
(returned from ldb_msg_canonicalize) wasn't freed
and stays attached to ldb_context for the connection lifetime.
