Subject: [PATCH] libads: abstract out SASL wrapping code
Prepare for rebasing libads on top of libsmbldap.
To make libads using 'struct smbldap_state' instead of direct LDAP
structure, we need to abstract out libads logic from connection
handling. SASL wrapping does not really depend on availability of LDAP
handle and does not need direct access to ADS_STRUCT. As result, we'll
be able to move SASL wrapping code under smbldap once the latter is able
to pass settings that libads passes to the SASL wrapping.
