Refactor dynamic DNS updates

Provides two new layers instead of the previous IPA specific layer:
 1) dp_dyndns.c -- a very generic dyndns layer on the DP level. Its
 purpose it to make it possible for any back end to use dynamic DNS
 updates.
 2) sdap_dyndns.c -- a wrapper around dp_dyndns.c that utilizes some
 LDAP-specific features like autodetecting the address from the LDAP
 connection.

Also converts the dyndns code to new specific error codes.
