Azure AD will set reserved_usn to zero when we expect it to be

We send the NC root first, as a special case for every chunk
that we send until the natural point where it belongs.
We do not bump the tmp_highest_usn in the highwatermark that
the client and server use (it is meant to be an opauqe cookie)
until the 'natural' point where the object appears, similar
to the cache for GET_ANC.
The issue is that without this, because the NC root was sorted
first in whatever chunk it appeared in but could have a 'high'
highwatermark, Azure AD Connect will send back the same
new_highwatermark->tmp_highest_usn, and due to a bug,
a zero reserved_usn, which makes Samba discard it.
The reserved_usn is now much less likely to ever be set because
the tmp_higest_usn is now always advancing.

This changes the GetNCChanges server to use a per-call state for
extended operations like RID_ALLOC or REPL_OBJ and only maintain
and (more importantly) invalidate the state during normal replication.
This allows REPL_OBJ to be called during a normal replication cycle
that continues using after that call, continuing with the same
highwatermark cookie.
Azure AD will do a sequence of (roughly)
* Normal replication (objects 1..100)
* REPL_OBJ (of 1 object)
* Normal replication (objects 101..200)
However, if there are more than 100 (in this example) objects in the
domain, and the second replication is required, the objects 1..100
are sent, as the replication state was invalidated by the REPL_OBJ call.
RN: Improve GetNChanges to address some (but not all "Azure AD Connect")

Move of strcasecmp redefine to lib/util/safe_string.h in

The reason for that is that ldb_attr_cmp() defined as

A solution is to add

strncasecmp.

safe_string.h which is in the source3-specific path. To accomodate
