Once RPC services are done by individual processes, we need to avoid
recursion between processes:
Any RPC server process will be able to serve multiple client requests
simultaneously, but each request is served in a single-threaded
blocking manner.
For example the netlogon RPC service needs to ask samr for
something. The netlogon->samr connection will initially be handled by
a central dispatcher assigning clients to processes. This dispatcher
needs to know that this connection can't end up in the same process
that originated the request.
With this flag an RPC client can request a samr server process that
exclusively serves its own requests and that will not serve anybody
else while serving netlogon.

This ensures the order of the struct element is the same as in the IDL

In many cases these can and should be consumed as soon as

This is not a complete fix, we don't clean up the array_size
token after using it split between an NDR_SCALARS and
an NDR_BUFFERS pass, but it is much better than it was
and helps the winbind case with a large number of groups
(eg 100,000) as otherwise we hit the 65535 NDR token limit.
(This is an arbitary Samba-only limit to avoid DoS conditions)

This makes it safer to change our code to remove tokens after use
if failing to obtain a token would result in an error.
