Add the early start of an async ldap library

There's a lot of things this does not do yet: For example it does not parse the
reply blob in the sasl bind, it does not do anything with controls yet, a lot
of the ldap requests are not covered yet. But it provides a basis for me to
play with a pdb_ads passdb module.
