This is used for allowing operations by RODCs, and denying them
operations that should only be allowed for a full DC
This required a new domain_sid argument to
security_session_user_level()

This function should not traverse the module stack again, but instead
run from this point. Also add a matching
dsdb_module_load_partition_usn() and change repl_meta_data to match.

This choses an appropriate talloc context to attach the schema too,
long enough lived to ensure it does not go away before the operation
compleates.

I used "unsigned int" counters where we count LDB objects (LDB specification
prescribes to use "unsigned" index variables).
But on DSDB replication object counters I used "uint32_t" typed variables as it
is suggested.
If a counter variable counts both types of objects I used "unsigned int" since
size(unsigned int) >= size(uint32_t), but on most platforms equal.
When updating replPropertyMetaData, check if the value being stored is
the same as the current value, and skip the update if it is.
This is based on a patch by Fernando J V da Silva <fernandojvsilva@yahoo.com.br>
It fixes the bug which causes an urgent replication to be enabled
incorrectly when an object is modified, but it should happen only
when it was created. This patch also fixes the bug that enable an
urgent replication when an object is deleted, but it should happen
only when it was modified and fixes the bug that does not enable
an urgent replication when an object is deleted and it should happen
only when it is deleted (not when it is modified).

This changes the meaning of the ->prev pointer in our doubly linked
lists to point at the end of the list from the front of the list. That
allows us to implement DLIST_ADD_END() and related functions in O(1)
time, which can be a huge saving in many places in Samba.
This also means that the 'type' argument to various DLIST_*() macros
is no longer needed, but I have left it in for now to keep the
patchset small, which will make it easier to revert if any problems
are found. In the future we should remove the 'type' arguments.
(jra. Move the one use of DLIST_TAIL over to the new macros).
When a object or attribute is created/updated/deleted, according
to [MS-ADTS] 3.1.1.5.1.6, it stores the uSNUrgent on @REPLCHANGED
for the partitions that it belongs.

We are using the values from a search result, so we need to steal them
onto the msg before we free the search results

We need DRS driven replication changes to update replPropertyMetaData,
so it needs to call into the repl_meta_data module logic
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
It is valid to get a NULL GUID over DRS for a deleted forward link. We
need to match by DN if possible when seeing if we should update an
existing link.

This uses the RELAX control and checking of single valued attributes
in ldb modules to avoid problems with multi-valued links where all
values but one are deleted
We need a separate RMD_LOCAL_USN to allow us to tell what attributes
need to be sent in a getncchanges request. Thanks to Metze for
pointing this out.

backlinks in add and delete operations can be processed immediately,
rather than at the end of a transaction. This can save on backlink
list processing time.
This implements repmld_delete(), which handles the meta_data updates
for an object when deleting. A delete gets mapped to a combination
of a rename followed by a modify request, which has the effect of
moving the object into the Deleted Objects container.
This is based on the code from Eduardo Lima
<eduardoll@gmail.com>. Eduardo's code was modified to take account of
the linked attributes changes that Andrew and I have been working on.

backlinks need more careful handling now that we store the additional
meta data for deleted links. It is easier to handle this in
repl_meta_data than in linked_attributes.
Eventually linked_attributes will disappear, with the functionality
moved into repl_meta_data.
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
We now have the core code for handling storage of linked attribute
meta-data with local modifies
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
When in functional levels above w2k, we need to store much richer meta
data about linkked attributes. We also need to keep deleted linked
attributes around to allow the deletion to be propogated to other DCs.
