libnet dssync: support lists of dns (instead of one dn) for single object replication.

dssync keytab: store the samaccountname in the keytab for diff replication.
When retreiving a diff replication, the sAMAccountName attribute is usually
not replicated. So in order to build the principle, we need to store the
sAMAccounName in the keytab, referenced by the DN of the object, so that
it can be retrieved if necessary.
It is stored in the form of SAMACCOUNTNAME/object_dn@dns_domain_name
with kvno=0 and ENCTYPE_NONE.

dssync keytab: move handling of removal of duplicates to libnet_keytab_add_entry().
This makes libnet_keytab_remove_entries static and moves it up.
libnet_keytab_add_entry() now removes the duplicates in advance.
No special handling neede for the UTDV - this is also needed
for other entries...

dssync: allow replications of a single obj with net rpc vampire keytab.
This is triggered by setting the new "single" flag in the dssync_context
and filling the "object_dn" member with the dn of the object to be
fetched.
This call is accomplished by specifying the DRSUAPI_EXOP_REPL_OBJ
extended operation in the DsGetNCCHanges request. This variant does
honor an up-to-date-ness vectore passed in, but the answer does not
return a new up-to-dateness vector.
Call this operation as "net rpc vampire keytab /path/keytab object_dn" .

dssync keytab: add support for keeping track of the up-to-date-ness vector.
The startup operation should get the old up-to-date-ness vector from the backend
and the finish operation should store the new vector to the backend after replication.
This adds the change of the signatures of the operations ot the dssync_ops struct
and the implementation for the keytab ops. The up-to-date-ness vector is stored
under the principal constructed as UTDV/$naming_context_dn@$dns_domain_name.
The vector is still uninterpreted in libnet_dssync_process().
This will be the next step...

dssync: replace the processing_fn by startup/process/finish ops.
This remove static a variable for the keytab context in the keytab
processing function and simplifies the signature. The keytab context
is instead in the new private data member of the dssync_context struct.
This is in preparation of adding support for keeping track of the
up-to-date-ness vector, in order to be able to sync diffs instead
of the whole database.

Enabled domain groups to be added to builtin groups at domain join time
Previously this was done at token creation time if the Administrators and Users
builtins hadn't been created yet. A major drawback to this approach is that if
a customer is joined to a domain and decides they want to join a different
domain, the domain groups from this new domain will not be added to the
builtins.
It would be ideal if these groups could be added exclusively at domain join
time, but we can't rely solely on that because there are cases where winbindd
must be running to allocate new gids for the builtins. In the future if there
is a way to allocate gids for builtins without running winbindd, this code
can be removed from create_local_nt_token.
- Made create_builtin_users and create_builtin_administrators non-static so
they can be called from libnet
- Added a new function to libnet_join that will make a best effort to add
domain administrators and domain users to BUILTIN\Administrators and
BUILTIN\Users, respectively. If the builtins don't exist yet, winbindd must be
running to allocate new gids, but if the builtins already exist, the domain
groups will be added even if winbindd is not running. In the case of a
failure the error will be logged, but the join will not be failed.
- Plumbed libnet_join_add_dom_rids_to_builtins into the join post processing.

Helper functions to enable domain groups to be added to builtin groups at domain join time
Added two new helper functions which wrap the raw pdb alias functions so they
can be more conveniently called while adding domain groups to builtin groups.
There were two bugs in those routines: They did not send INTERNAL_OPEN_ONLY to
open_file_ntcreate() and they did not chdir, so the file could never be found.
While there I decided to remove the become_root() calls and call create_file()
instead of the lower-level routines.

Fix a race condition in winbind leading to a crash
When SIGCHLD handling is delayed for some reason, sending a request to a child
can fail early because the child has died already. In this case
async_main_request_sent() directly called the continuation function without
properly removing the malfunctioning child process and the requests in the
queue. The next request would then crash in the DLIST_ADD_END() in
async_request() because the request pending for the child had been
talloc_free()'ed and yet still was referenced in the list.
