This needs to be more async, and give less scary errors.

We don't behave completely like a Windows server, but it's much more
identical than before.
The partition head is always the first object followed by the rest
sorted by uSNChanged.

We should build the final highwatermark and uptodatevector of
a replication cycle at the start of the cycle. Before we
search for the currently missing objects.
Otherwise we risk that some objects get lost.

replication cycle (bug #9508)
If the highwatermark given by the client is not the one we expect,
we need to start a new replication cycle. Otherwise the destination dsa
skips objects and linked attribute values.

Paragraph 4.1.10.5 says that
if err = 0 then
msgOut.pNC := msgIn.pNC
msgOut.usnvecFrom := msgIn.usnvecFrom
so no need to set the highestUsn to 0

As this value is calculated new each time, we need to give it a context to live on.
If the value is the forced value during provision, a reference is taken.
This was responsible for the memory leak in the replication process. In the
example I was given, this DN appeared in memory 13596 times!

unefficient
Current implementation of ldb_msg_find_attr_as_* iterate on the list of
attributes returned by the search and make a string comparison. As we
sorting the array of messages / guids we tend to call this function many
times. By storing the GUID and the USN in a separate structure we are
sure to call this function only once per attribute and object.

Having a false value cause the link on removed attribute to be always
returned which is what we try to avoid.

when a DC has the GUID_DRS_GET_FILTERED_ATTRIBUTES right on a NC, we
need to allow it to replicate if all the attributes it is asking for
are in the GC partial attribute set

When an object is deleted, link pointed to it are marked as inactive.
When the same object is purged we do not remmove the link pointed to it
(we can't know them) so they stay in the database, it turns to be a
problem for Windows 2008.

we now keep just a list of GUIDs around between getncchanges calls,
instead of an entire db search. This makes the overhead of having a
pending getncchanges call much smaller.

Those values are actually ATTID values and such, they are used

This implements partial attribute set checking on getncchanges. If the
client sends a partial_attribute_set then we only return the specified
attributes.
This also implements access checking on the NC root for the access
right GUIDs for requests with and without reveal secrets
