ffb8b50e3c s4-rpc_server: Allow each interface to declare if it uses handles
This will allow the NETLOGON server in the AD DC to declare that it does not use
handles, and so allow some more flexibility with association groups

1edf3d89c4 s4:rpc_server: process all provided presentation contexts
We should respond with an explicit result for each presentation context,
while we also accept one new context per BIND/ALTER_CONTEXT.

For now we still only support NDR32, but adding NDR64 should
be fairly easy now.
